Answer:
8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16
Step-by-step explanation:
The outer rectangle has width 8 and length 3y + 2.
The area of the outer rectangle is length times width or width times length, so the area is 8(3y + 2).
We can also find the area by finding the area of each small rectangle, and adding the areas together.
The left small rectangle has dimensions 8 and 3y.
A1 = WL = 8 * 3y = 24y
The right small rectangle has dimensions 8 and 2.
A2 = WL = 8 * 2 = 16
The total area of both small rectangles is 24y + 16
That tells use that
8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16
This is the distributive property at work.
When transforming a figure by dilation, the scale factor will be multiplied to the x and y points of the figure.
Given:
a.) The square is dilated by a scale factor of 2.5.
Given the scale factor of 2.5. The new coordinates of the resulting square must be:
Therefore, the answer is letter A.
Answer:
1.
( n + 4 ) - 9
- n - 4 - 9
- n - 13
2.

19) because 1/2 an hour is 8 miles, 1 hour will take 16 miles , multiply 8 by 2 because I️t gave half an hour so multiplying by 2 will give an hour (2 half’s make a whole)
20) 2 1/2 multiplied by 4 is 10, so his jog will be 10 minutes longer
21) 4,500 was what he earned and 4,900 was what he lost (“expenses”) so he lost $400:
$4,500 - $4,900= -$400
He lost money because the answer is negative
