Answer:
Step-by-step explanation:
X^2 and 9 are two squares, while 6 can be obtain my multiplying x and 3 by 2.
so this is a square of a binomial
(x+3)^2
or
(x+3)(x+3)
Answer:
(x+3)², if looking for x, X = -3
Step-by-step explanation:
X²+6x+9 is a perfect square as you immediately can see that 3+3 = 6 and 3*3 = 9.
I used the generic rectangle to solve it, 9 into top right corner and then x² onto the bottom left, multiplying eachother to get 9x² which is formed by 3x and 3x multiplied so you would have (x+3) (x+3).
I'll have a picture.

Paul is comparing two high-speed Internet service providers (ISPs) for his business. The graph represents the cost of each ISP as a function of t, the duration in months of a service contract.
A coordinate grid showing Internet Service Provider Cost, with Service Contract in months along the horizontal axis, and Total Cost in dollars along the y-axis. Two lines are graphed. One line is labeled I S P A and passes through (0, 180) and (12, 300). The second line is labeled I S P B and passes through (0, 0) and (12, 300).
If C(t) = 180 + 10t represents ISP A and C(t) = 25t represents ISP B, how long would the service contracts need to be for the total costs to be the same?
6 months
8 months
10 months
12 months
Answer:
12 months
Step-by-step explanation:
Theres an awful amount of needless information to get through.
Only the last paragrph is needed.
C(t) = 180 + 10t
C(t) = 25t
Set the equations equal
25t = 180 + 10t
Subtract 10t from both sides
15t = 180
Divide both sides by 15
t = 12
Answer:
12 months

Solve for x.
(3x - 1)2 = 25
Answer:
9/2
Step-by-step explanation:
2(3x - 1) = 25
6x - 2 = 25
6x = 27
x = 9/2
Solve for x. Enter the solutions from least to greatest. (x−1)^2−9=0
Step-by-step explanation:
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}

Answer:
(7, 4)
Step-by-step explanation:
The solution to the system of the 2 equations represented on the graph by the two lines is the c
x and y coordinates of the point where the two lines intersect.
They intersect at when x = 7, y = 4.
Therefore, the solution to the system of equations would be (7, 4).
Lydia buys peanut butter in bulk for $0.20 an ounce. How much does 18 ounces of the peanut butter cost?
Answer:
3.6 dollars
Step-by-step explanation:
Lets go over what we know:
Each ounce of penut butter cost 0.2$, or 1/5$
We need 18 ounces.
To solve this, lets multiply the cost per ounce by the amount of ounces:
0.2*18
Or
1/5*18
=
18/5
This can be simplfied into:
3 3/5
We know each 1/5 is 20 cents(0.2), so 3 cents would be 3*0.2 = 0.6:
3.6 dollars
So the answer is for 18 ounces, it cost 3.6 dollars.
Hope this helps!

What is the area, in square centimeters, of an equilateral triangle with a perimeter of 15 centimeters? Round the answer to the nearest tenth.
Answer:
A≈10.83cm²
Step-by-step explanation:
Unit Conversion:
P=15cm
Using the formulas
A=3
4a2
P=3a
Solving forA
A=3P2
36=3·152
36≈10.82532cm²
Answer:
10.8 cm^2 to nearest tenth.
Step-by-step explanation:
You can use Hero's formula to do this:
Area = √[s(s-a)(s-b)(s-c)] where s = semi-perimeter, a b and c are the lengths of the 3 sides,
Here s = 15/2 = 7.5 and a, b and c = 5.
area = √(7.5 * 2.5 * 2.5 * 2.5)
= √117.1875
= 10.8253.
Another method would be to use trigonometry
h = 5 sin 60 and 1/2 * base = 1/2 * 5 = 2.5
So area = 5 sin60 * 2.5 = 10.8253,

The following tables show some values from three different functions. which of these functions could be quadratic?
Answer:
C. III only
Step-by-step explanation:
a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.
so, let's look at the tables.
table I shows the powers of 2. y = 2^x
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
so, it is not saying anything in general.
table II shows an "identity" equation. y = x
0 = 0
1 = 1
2 = 2
3 = 3
this does not square anything.
table III shows then finally a square equation. y = x^2
0^2 = 0
1^2 = 1
2^2 ≈ 4
3^2 = 9

4. If f(x)=2x+3(x+4)+5 then f(6)=?
Answer:
f(6)=42
Step-by-step explanation:
We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.
If this has helped please mark as brainliest
Answer: 47
Step-by-step explanation:
That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.

Answer:
[tex]\frac{96}{91}[/tex] or 51.69
Step-by-step explanation:
[tex]\frac{-6}{13}[/tex] x reciprocal of [tex]\frac{-7}{16}[/tex]
Reciprocal of [tex]\frac{-7}{16}[/tex] is [tex]\frac{-16}{7}[/tex]
So, the equation would be:-
[tex]\frac{-6}{13}[/tex] x [tex]\frac{-16}{7}[/tex]
= [tex]\frac{96}{91}[/tex]
The product would be [tex]\frac{96}{91}[/tex].

What is the sum of the of what is the sum of the given arithmetic series?
5 + 8 + 11 + ... + 92
O 1554
O 1545
O 1455
O None of these
Answer:
3rd option : 1455
Step-by-step explanation:
here, a = 5, d = 3 , tn = 92, n = ?, Sn = ?
tn = [a + (n - 1) d]
92 = [ 5 + (n - 1)d
92 = 5 + 3n - 3
92 - 5 + 3 = 3n
90 = 3n
n = 90/3
n = 30
By sum of first n terms of an A. P formula,
Sn = n/ 2 [ 2a + (n - 1) d]
Sn = 30/2 [ 2 * 5 + (30 - 1) 3]
Sn = 15[ 10 + 29 ( 3) ]
Sn = 15[ 10 + 87 ]
Sn = 15( 97 )
Sn = 15 * 97
Sn = 1455
Therefore, option 3rd 1455 is correct.
