1.The area of Sandy's yard is 25x^2 - 625 ft^2. A patch of sod has an area of x^2 - 10x + 25 ft2. Divide the two areas and simplify to find how many pieces of sod Sandy needs to cover her yard, in terms of x. 2. If x = 6 ft^2, what is the area of Sandy's yard? 3. If x = 6 ft^2, what is the area of a patch of sod?
