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)
wow!!! that was so fast. Thank you so much!
So the answer is 6x+4, right?
(just happened to be on the computer)
Thank you!!! :)
