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? (5x−2)+(3x+1); 31 centimeters (5x−2)+(3x+1); 36 centimeters 2(5x−2)+2(3x+1); 62 centimeters 2(5x−2)+2(3x+1); 70 centimeters

Mercury:

L = 5x – 2 W = 3x + 1 formula for the perimeter of a rectangle: 2L + 2W plug in (5x – 2) for L and (3x + 1) for W into the the perimeter equation. now, since it asks for the perimeter at x = 4, plug in x = 4 and evaluate.
