Question

The perimeter of a rectangle is 16x – 6. If the length is
5x + 2, what is the width?

Answer 1

w = 3x - 5

Explanation:

Perimeter of a rectangle formula:

P = 2(l + w)

16x - 6 = 2(5x + 2 + w)

16x - 6 = 10x + 4 + 2w

2w = 16x - 6 - 10x - 4

2w = 6x - 10

w = 3x - 5

Answer 2

3x + 1

Explanation:

5x + 2 × 2 = 10x + 4

do this take 16x - 6

you get 6x + 2

then divide by 2 to get the answer 3x+1
