6-39.

Ms. Cai’s class is studying a tile pattern. The rule for the tile pattern is

*y*= 10

*x*+ 8. Kalil thinks that Figure 12 of this pattern will have 108 tiles. Is he correct? Justify your answer. Homework Help ✎

*y* = # of tiles*x* = Figure #

Substitute the information from the problem into the equation *y* = 10*x* + 8.

Kalil is wrong.

108 = 10(12) + 8

108 = 120 + 8

108 ≠ 128 tiles
