**Reiny**, Tuesday, November 16, 2010 at 5:27pmwidth of pool ---> x

length of pool --> x+7

area of pool = x(x+7)

width of whole pool area = x+3

length of whole pool area = x+7+3 = x+10

area of pool area = (x+3)(x+10)

area of concrete walkway = area of whole thing - area of pool

solve

120 = (x+3)(x+10) - x(x+7)

etc.

(you should get x = 15)
