Alright, thanks.

A film 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 <<My answer
12x4y6
