Answer:
= 25x² - 40x + 16
Step-by-step explanation:
(5x - 4)²
= (5x - 4) (5x - 4)
= 25x² - 20x - 20x + 16
= 25x² - 40x + 16

Answer:
Step-by-step explanation:
find the labeled points
Answer:
A= (6,76.5)
B =(32,18)
C=(80,0)
Step-by-step explanation:
The inequalities given are ;
3x + 8y ≥ 240
9x + 4y ≥ 360
x≥6
y≥0
The graph for the inequalities is as follows;
From the graph,
A= (6,76.5)
B =(32,18)
C=(80,0)
1) x < -14
please help i don’t know how to do this
Answer: See the diagram below.
This diagram shows a closed filled in circle at -14 on the number line. Also, the shaded region is to the left of the closed circle. This visually represents values that are smaller than -14, or equal to -14.
The filled in circle is used to indicate "include this endpoint". In contrast, an open hole indicates "do not include this endpoint" which is only used if the inequality was [tex]x < -14[/tex] instead of [tex]x \le -14[/tex]. The "or equal to" portion is why we include the endpoint.
Solve the following proportions p/18= 8/72 pls help
Answer:
p = 2
Step-by-step explanation:
[tex]\frac{p}{18}[/tex] = [tex]\frac{8}{72}[/tex]
to work with smaller numbers you can look to reduce
for example, 8/72 can be reduced to 1/9
[tex]\frac{p}{18}[/tex] = [tex]\frac{1}{9}[/tex]
now you can cross-multiply:
9p = 18
p = 18/9 which is 2

Suppose your friend's parents invest $15,000 in an account paying 7% compounded annually. What will the balance be after 10 years?
Answer:
$25,500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation
I = 15000 × 0.07 × 10 = 10500
I = $ 10,500.00
The simple interest accumulated
on a principal of $ 15,000.00
at a rate of 7% per year
for 10 years is $ 10,500.00.

ZA and ZB are supplementary angles. If mZA = (x + 6) and m
ZB = (7x +30)°, then find the measure of ZA.
Answer:
za=24
Step-by-step explanation:
supplementary angles add up to equal 180
180=7x+x+30+6
step 1 combine like terms
180=8x+36
step 2 subtract 36 from each side
144=8x
step 3 divide each side by 8
x=18
now we just plug in 18 to x in x+6
18+6=24
Answer:
24°
Step-by-step explanation:
The sum of supplementary angles is 180°.
Thus, we can set up our equation as:
(x + 6) + (7x + 30) = 180
Combine like terms.
8x + 36 = 180
Isolate the variable by subtracting 36 from both sides.
8x = 144
Divide both sides by 8.
x = 18
Now, let's revisit the equation for m∠ZA, and plug in our x.
((18) + 6)°
24°
If m= 3 and n= 2, then m2-n2 is equal to
Answer:
5
Step-by-step explanation:
(I'm assuming that by m2 and n2 you mean m to the power of 2 and n to the power of 2)
Whenever you have a number to a power, it is the same as that number times itself that power number of times. For example, 3 to the power of 4 is equal to 3 times itself 4 times, which is 3 * 3 * 3 * 3. If we use this and substitute the values in for m and n, we get that 3^2 - 2^2, and since 3^2 is 3 * 3 and 2^2 is 2 * 2 and 3 times 3 is 9 and 2 times 2 is 4, we get that 9 - 4 is 5.
Note: This symbol means to the power of ----> ^

Is 6x and 4x+2 equivalent
Answer:
Is 6x and 4x+2 equivalent
? No!
Step-by-step explanation:
6x doesn't equal 4x+2
In order for them to be the same you would have to add the same terms example:
4x+2x would equal 6x
Extra explaining:
The only way for those term to be added would be if they had the same variable since only 4x has a variable the 2 cant be added. In math you CANNOT move your variables off of a number and add them back on after.

Step-by-step explanation:
A carpenter has $60 with which to buy supplies. The carpenter needs to buy both nails
and screws. Nails cost $12.99 per box, and screws cost $14.99 per box. If n represents the
number of boxes of nails and s represents the number of boxes of screws, which of the
followina sustems of inequalities models this situation?
Answer:
$12.99n + $14.99s = $60
Step-by-step explanation:
The system of inequalities is n ≥ 1 and s ≥ 1 would represent this situation.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
Let n represent the number of nail boxes and s represent the number of screw boxes.
Nails will cost $12.99 if the price per box is $12.99.
In a similar vein, if a screw costs $14.99 a box, then s screws will also cost $14.99.
The carpenter can purchase n nails and s screws for a total of $60.
12.99n + 14.99 ≤ 60
Also, Since the carpenter needs to buy both nails and screws, it is necessary to buy at least 1 box of each of the two materials.
Therefore, the system of inequalities is n ≥ 1 and s ≥ 1 would represent this situation.

The following information is known about a loan.
Time = 7 years
Interest rate = 6%
Interest = $840.00
What was the principal on the loan?
$200.00
$352.8ghing
$1.862.50
O $2.000.00
Answer:
B. $352.80
Step-by-step explanation:
edge 2021
The principal on the loan with interest rate of 6% is $2000.
Given that a loan is given in the interest rate of 6%, interest received is $840 and the duration of the loan is 7 years,
We need to find the principal on the loan,
To find the principal on the loan, we can use the formula for simple interest:
Interest = Principal × Rate × Time
In this case, we know the interest is $840.00, the rate is 6%, and the time is 7 years.
Let's solve for the principal:
Principal = Interest / (Rate × Time)
Principal = $840.00 / (0.06 × 7)
Principal ≈ $840.00 / 0.42
Principal ≈ $2000.00
Therefore, the principal on the loan is $2000.00.
