Question

Ms cais class is studying a study pattern.the rule for the tile pattern is y=10x-18.kalil thinks that figure 12 of this pattern will have 108 tiles is he correct justify your answer

Answer 1

I assume that x = figure no.

It's better to write this as

Tiles = 10n-18

Thus 10(12) - 18

=120 - 18

= 102

THUS HE IS WRONG.
