A rectangle’s length is 5 inches more than twice its width. Its area is 50 square inches. Which equation can be used to find its width, w?

The width is w, so twice the width is 2w. The length is 5 inches more than that, or 2w + 5. Since area equals length times width, the equation is w(2w + 5) = 50, which is choice C.
