Question

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 (3xy)(7xy2), 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?

21xy2

21xy3

21x2y2

21x2y3

Answer 1

D - 21x2y3

Answer 2

21x^2y^3

Answer 3

thanks but do you guys have anywork so I can do it better next time

Answer 4

any work*

Answer 5

Well, you start with the equation given:
(3xy)(7xy2)
And multiply the numbers for the first parenthesis to the numbers from the second parenthesis.

3x X 7x = 21x
y X y = 2y
and so on.

Which is how you get the answer: 21x2y3
