Question

the length of a rectangle is represented by 3x-7 and the width by x+4. express the perimeter as a polynomial in simplest form

Answer 1

Answer: 8x - 6

Explanation:

Perimeter is found by doing 2l + 2w

The length is 3x - 7 and width is x + 4

2(3x - 7) + 2(x + 4) =

6x - 14 + 2x + 8 =

8x - 6
