Chad had a garden that was in the shape of a rectangle. Its length was twice its width. He decided to make a new garden that was 2 feet longer and 2 feet wider than his first garden. If x represents the original width of the garden, which expression represents the difference between the area of his new garden and the area of the original garden?

  original garden is (x)(2x) = 2x^2 new garden = (x+2)(2x+2) = so difference = (x+2)(2x+2) - x(2x)
