Any one smart enough to answer me (a-b) (a+2b) ?
Answer:
ok lets do it..
Step-by-step explanation:
You simply multiply out each factor.
So you start by multiplying the a in (a+b) to each term in (a−2b).
You will get a2−2ab as the first portion of the answer.
So now you will do the same with the b in (a+b).
Then you get −2b2+ab.
Now you add a2−2ab and −2b2+ab to get a2−2b2−ab .
i hope it will work....
Answer:
a² + ab - 2b²
Step-by-step explanation:
Given
(a - b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) - b(a + 2b) ← distribute both parenthesis
= a² + 2ab - ab - 2b² ← collect like terms
= a² + ab - 2b²
Pls help asapppp I dint know the answer and I’m running out of time
Step-by-step explanation:
I can barely see the questions
The segment JL has a definite length of [Drop Down 1]. Segments JK and KL have both definite lengths of [Drop Down 2] and [Drop Down 3], respectively. Both segments are [Drop Down 4]. JL=5x-9, JK=3x and KL=1x+4
Answer:
[tex]JL=56[/tex] [tex]JK=39[/tex] [tex]KL=17[/tex]
Step-by-step explanation:
Your question is not well presented/formatted; however, I can deduce that the question requires that you calculate the following lengths;
JK, KL and JL
Given that
[tex]JL=5x-9[/tex]
[tex]JK=3x[/tex]
[tex]KL=1x+4[/tex]
The relationship between the given parameters is:
[tex]JL = JK + KL[/tex]
Substitute 5x - 9 for JL; 3x for JK and 1x + 4 for KL
[tex]5x - 9 = 3x + 1x + 4[/tex]
Collect Like Terms
[tex]5x - 3x - 1x = 9 + 4[/tex]
[tex]x = 13[/tex]
Now that the value of x has been solved, we can easily get the numeric values of JK, KL and JL by substituting 13 for x
So;
[tex]JL=5x-9[/tex]
[tex]JL=5*13-9[/tex]
[tex]JL=65 - 9[/tex]
[tex]JL=56[/tex]
[tex]JK=3x[/tex]
[tex]JK=3 * 13[/tex]
[tex]JK=39[/tex]
[tex]KL=1x+4[/tex]
[tex]KL=1 * 13+4[/tex]
[tex]KL=13+4[/tex]
[tex]KL=17[/tex]
Hence;
[tex]JL=56[/tex] [tex]JK=39[/tex] [tex]KL=17[/tex]
What is the real number value of m^3+ √12 m when 5m^2 = 45 ?
F. 15
G. 27
H. 33
J. 38.09
K. 739.39
=============================================
Work Shown:
Solve 5m^2 = 45 for m to get
5m^2 = 45
m^2 = 45/5
m^2 = 9
m = sqrt(9)
m = 3
I'm making m to be positive so that way the expression 12m is not negative. Otherwise, sqrt(12m) would not be a real number result.
--------------
Plug m = 3 into the expression we want to evaluate
m^3 + sqrt(12m)
3^3 + sqrt(12*3)
27 + sqrt(36)
27 + 6

Answer:
Answer of 15(i) is the picture . 15(ii) and 17 are solved
Step-by-step explanation:∆ABC where B=90°
→D is mod point of BC so CD=BD
To Prove:
→BC^2=4(AD^2-AB^2)
PROOF:--
In ∆ABD by pythagorus theorem we get,
AD^2=AB^2+BD^2
SO
➡️BD^2= AD^2-AB^2. (1)
NOW ,
BC= BD+CD
BC= 2BD (AS D IS MID POINT)
SQUAREING BOTH SIDES
BC^2= 4BD^2
BY EQUATION 1 WE GOT BD^2 = AD^2-AB^2
Putting this value
➡️BC^2= 4(AD^2-AB^2)
HENCE PROVED
-------------------------------------------------------------------------
17.
Construction : Draw AE ⊥ BC
Proof : In ∆ABE and ∆ACE, we have
AB = AC [given]
AE = AE [common]
and ∠AEB = ∠AEC [90°]
Therefore, by using RH congruent condition
∆ABE ~ ∆ACE
⇒ BE = CE
In right triangle ABE.
AB2 = AE2 + BE2 ...(i)
[Using Pythagoras theorem]
In right triangle ADE,
AD2 = AE2 + DE2
[Using Pythagoras theorem]
Subtracting (ii) from (i), we get
AB2 - AD2 = (AE2 + BE2) - (AE2 + DE2)
AB2 - AD2 = AE2 + BE2 - AE2 - DE2
⇒ AB2 - AD2 = BE2 - DE2
⇒ AB2 - AD2 (BE + DE) (BE - DE)
But BE = CE [Proved above]
⇒ AB2 - AD2 = (CE + DE) (BE - DE)
= CD.BD
⇒ AB2 - AD2 = BD.CD
Hence Proved.
PART A :A deli receives a large order for sandwiches for a company picnic. The company wants one club sandwich and two regular sandwiches for each person. The company also wants an extra Dagwood sandwich. A club sandwich has $3$ slices of bread. A regular sandwich has $2$ slices. A Dagwood has $5$ slices. If there are $n$ people going to the company picnic, how many slices of bread does the deli need to make this order? Write your answer as a fully simplified expression. Your answer should have the variable $n$ in it exactly once. PART B: Given that the deli ends up using $110$ slices of bread, how many people are going to the company picnic?
Answer:
Part A:
[tex]7n + 5[/tex]
Part B:
15 people
Step-by-step explanation:
Each person gets one club sandwich and two regular sandwiches. There is one additional Dagwood sandwich.
If a club sandwich has 3 slices, then the total amount of slices needed for [tex]n[/tex] people will be [tex]3n[/tex], since each person has 3 slices.
If a regular sandwich has 2 slices and everybody gets 2 regular sandwiches, then it's represented as [tex]4n[/tex], since everyone has 4 slices each.
Additionally, we have one Dagwood sandwich, which can be represented as 5,, since a Dagwood sandwich has 5 slices.
Combining these terms we get [tex]3n + 4n + 5[/tex]. Combining like terms gets us the expression [tex]7n + 5[/tex].
To solve for [tex]7n + 5[/tex], we have to make it an equation. Using the information in Part B, the Deli ends up receiving 110 slices of bread. So, the equation is
[tex]7n + 5=110[/tex]
We want to isolate n on one side, to do this we have to subtract 5 then divide by 7.
[tex]7n + 5 - 5= 110-5\\\\7n = 105\\\\7n\div7 = 105\div7\\\\n = 15[/tex]
So 15 people are going to the picnic.
Hope this helped!

To estimate the percentage of defects in a recent manufacturing batch, a quality control manager at Toshiba selects every 12th laptop that comes off the assembly line starting with the ninth until she obtains a sample of 110 laptops. What type of sampling is used?
a. Simple random
b. Stratified
c. Convenience
d. Systematic
e. Cluster
Answer:
D) systematic
Step-by-step explanation:
Systematic sampling. With systematic random sampling, one creates a list of every member of the population, and from the list, one can randomly select the first sample element from the first Nth elements on the population list. Thereafter, we select every Nth element on the list. Selection is done according to a random starting point but with a fixed, periodic interval. This interval, which is called the sampling interval, is calculated by dividing the population size by the desired sample size.

Answer:
x^2 +6x -15
Step-by-step explanation:
(3x^2 +2x -8) - (2x^2 -4x+7)
Distribute the minus sign
(3x^2 +2x -8) - 2x^2 +4x-7
Combine like terms
x^2 +6x -15
Answer:
x²+6x-15
Step-by-step explanation:
We are given this expression:
[tex](3x^2+2x-8) - ( 2x^2-4x+7)[/tex]
We want to simplify the expression. First, distribute the negative sign in front of the second set of parentheses. Multiply each term inside the parentheses by -1.
[tex](3x^2+2x-8) + (-1*2x^2) + (-1*-4x) + (-1*7)[/tex]
[tex](3x^2+2x-8) -2x^2+ 4x -7[/tex]
Next, combine like terms. The 2 terms with an x² can be combined, just like the two terms with an x, and the two terms without a variable.
[tex](3x^2-2x^2) + (2x+4x) + (-8-7)[/tex]
[tex]x^2+(2x+4x)+(-8-7)[/tex]
[tex]x^2+6x+(-8-7)[/tex]
[tex]x^2+6x-15[/tex]
The expression x²+6x-15 is equivalent to (3x²+2x-8)-(2x²-4x+7)

PLEASE HELP! I will mark as brainliest if you help me. Solve for x. −ax + 2b > 8
Answer:
x < ( 8 - 2b ) / -a
Step-by-step explanation:
For this problem, we simply will solve the inequality for x.
-ax + 2b > 8
-ax > 8 - 2b
x < ( 8 - 2b ) / -a
Note, the comparison is flipped since a negative multiplicand was used to isolate x.

Wakaba buys some granola bars at $0.50 each and energy drinks at $2 each for a group hike. She buys twice as many granola bars as energy drinks. If she spends $27 in total, how many granola bars and energy drinks does she buy?
Answer: 9 energy drinks and 18 granola bars.
Step-by-step explanation:
Price per granola bar = $0.50
Price per energy drink = $2.
We can define G as the number of granola bars that she bought, and D as the number of drinks that she bought.
Then
"She buys twice as many granola bars as energy drinks."
G = 2*D
" If she spends $27 in total"
G*$0.50 + D*$2 = $27
So we have a system of equations:
G = 2*D
G*$0.50 + D*$2 = $27
The first step will be to replace the first equation into the second one, and solve it for D.
(2D)*$0.50 + D*$2 = $27
D*(2*$0.50) + D*$2 = $27
D*$1 + D*$2 = $27
D*$3 = $27
D = $27/$3 = 9.
So she bought 9 energy drinks, and we know that:
G = 2*D
G = 2*9 = 18
She bought 18 granola bars.

collinear
coplanar
both collinear and coplanar
neither collinear nor coplanar
Answer:
Option (4)
Step-by-step explanation:
Coplanar points-
If two or more points are in the same plane, points are called to be coplanar points. Three points in space are always coplanar.
Collinear points-
If two or more points are on a straight line, points are collinear.
Two points are always collinear.
From the diagram attached,
Points R,T,Q and S are neither coplanar nor collinear.
Therefore, Option (4) will be the answer.
Answer:

Step-by-step explanation:
Marlon is bowling in a tournament and has the highest average after 5 games, with scores of 210, 225, 254, 231, and 280. In order to maintain this exact average, what must be Marlon's score for his 6th game?
Answer:
By scoring 240 in the sixth game, Marlon can maintain this exact average
Step-by-step explanation:
The first thing to do here is to calculate the average for the first 5 games.
Mathematically, the average can be calculated by adding all the scores in the games and dividing by 5;
= (210 + 225 + 254 + 231 + 280)/5 = 1200/5 = 240
Now to maintain this average score of 240, we want to know the score she must have in the 6th game.
Let the score be x;
By adding x to the previous total of 1200 before and dividing by the new count of 6, we can work our way to get x.
Mathematically, what we are saying is;
(1200 + x)/6 = 240
6 * 240 = 1200 + x
1440 = 1200 + x
x = 1440 -1200
x = 240
