Question

The length of a rectangle is 6 inches longer than its width. The perimeter of the rectangle is 28 inches. If x represents the width of the rectangle, which equation can be used to find its value? x + 6 + 2x = 28 6x + 6x + x + x = 26 2(x + 6) = 28 2(x + 6) + 2x = 28

Answer 1

D:2(x+6)+2x=28

Explanation:

The width is x. The length is x+6. The formula for the perimeter of a rectangle is 2l+2w. Input our knowns.
