Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. Which expression can be used to find the perimeter of the rectangle and what is the perimeter if x = 4?

A rectangle’s perimeter is twice its length plus twice its width: 2(5x − 2) + 2(3x + 1). For x = 4, the length is 5(4) − 2 = 18 and the width is 3(4) + 1 = 13. The perimeter is 2(18) + 2(13) = 62 centimeters, so the correct choice is C.
