Question

A rectangle has length 3x + 4 and width 2x - 1. What is the perimeter of the rectangle?

Answer 1

the width is 10x + 6

Explanation:

but we know for a rectangle that the length and the width added twice together equals the perimeter . so you will want to do 2(3x+4)+2(2x-1) which equals 6x+8+4x-2 which equals 10x+6.
