Afilm set designer is using white and colored tiles in a pattern to create paths of different lengths. if x is the length of the path in feet, the number of colored tiles needed to make it is calculated using the rule (4x2y3)(3x2y2) where y represents the number of white tiles. which simplified expression represents the number of colored tiles used for a path of length x feet? 7x4y5 7x4y6 12x4y5 12x4y6
