How would I use the distributive property to rewrite (9-p)3 and then simplify?
Answers
3(9-p)
2.To distribute, you just take the term on the outside of the parentheses and multiply it with each term on the outside (seperately)
3 * 9 = 27
3 * -p = -3p
3. This would leave you with the following equation...rewrite it with the letters first.
-3p + 27 or 3p - 27
either way works!

What is the solution to the equation? 4y – 12 = –4 A. y = 11 B. y = 2 C. y = –4 D. y = –13
Answer:y=2
4y+-12=-4
Reorder the terms:
-12+4y=-4
Move all terms containing "y" to the left, all other terms to the right.
Add 12 to each side of the equation:
-12 + 12 + 4y = -4 + 12
Combine like terms:
-12 + 12 = 0
0 + 4y = -4 + 12
4y = -4 + 12
Combine like terms:
-4 + 12 = 8
4y = 8
Divide each side by '4'.
y = 2
So your answer is B Y=2

33 goes on top because the number adjacent to a box at the bottom is added up to make the box above it that overlaps it. 3+4=7, 7+9=16, and 16+17=33.
Final answer:
In mathematics, the number that goes on top is typically the numerator in a fraction. It represents the number of parts we have or the value we are considering. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator.
Explanation:
In mathematics, the number that goes on top is typically the numerator in a fraction. In a fraction, the numerator represents the number of parts we have or the value we are considering. The denominator, which goes on the bottom, represents the total number of equal parts that make up a whole.
For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator. This means we have 3 out of 4 equal parts.
So, depending on the context, the number that goes on top could be the numerator in a fraction or the value we are considering in a mathematical expression.

Answer:
x = 14, y= -3
Step-by-step explanation:
Solve the following system:
{2 x + 8 y = 4 | (equation 1)
{x = 5 - 3 y | (equation 2)
Express the system in standard form:
{2 x + 8 y = 4 | (equation 1)
{x + 3 y = 5 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + 8 y = 4 | (equation 1)
{0 x - y = 3 | (equation 2)
Divide equation 1 by 2:
{x + 4 y = 2 | (equation 1)
{0 x - y = 3 | (equation 2)
Multiply equation 2 by -1:
{x + 4 y = 2 | (equation 1)
{0 x+y = -3 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{x+0 y = 14 | (equation 1)
{0 x+y = -3 | (equation 2)
Collect results:
Answer: x = 14, y = -3

° is the measure of ∠
.
° is the measure of ∠
.
Step-by-step explanation:
Given that,
is the measure of ∠
.
Now,
The measure of ∠ is forty degree less than that of ∠
, so (
) is the measure of ∠
.
The measure of ∠ is ten degree less than twice that of ∠
, so (
) is the measure of ∠
.
So,
According to Angle sum property,
Sum of the measures of the three angle of triangle is °.
Now,
∠ + ∠
+ ∠
=
°
() + (

2. Find the absolute value of differences between each data an the mean:
1) |-7 -(-1)| = |-7 + 1| = |-6| = 6
2) |-2-(-1)| = |-2+1| = |-1| = 1
3) |1 -(-1)| = |1+1| = |2| = 2
4) |4 -(-1)| = |4+1|=|5|=5
3) Calculate the mean of those differences:
( 6 + 1 + 2 + 5) / 4 = 14/4 = 3.5
