The perimeter formula for a rectangle is 2l + 2w, where l is the length and w is the width. complete the steps to find an expression that represents the perimeter of the rectangle. substitute the expressions for length and width into the formula 2l + 2w. distribute 2 to each term in the parentheses. combine like terms. inches

1. 2(8x – 1) + 2(2x + 4)

2. 16x – 2 + 4x + 8

3. (20x + 6)

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
