an l shaped strip x inches wide is cut from a piece of cardboard 8inches by 10 inches. write the particular equation for the area of the remaining piece of cardboard as a function of x(no not use l or w).
-------------------
Area = L*W = 8*10 before the cut
After the cut, L = 10-x and W = 8-x
Area = (10-x)*(8-x)
Area+=+80+-+18x+%2B+x%5E2
