8-101.

Adriel and Gustavo were playing a game with algebra tiles. As they compared them, they were left with the following expressions on their mats. Use legal moves to simplify what is on the mats. Be sure to record your work in a way that others can understand.

Can you determine which side has the greater value? If so, show why. If not, for what values of *x* is Mat A larger?
