Answer:
-45m + 64
Step-by-step explanation:
To solve this, we are going to eliminate the parenthesis first:
(–9m + 12) –6m + 12 –6m + 8 –6m + 24 –18m + 8
= -9m + 12 - 6m + 12 –6m + 8 –6m + 24 –18m + 8
Now we're going to sum up all the terms that have an "m" and all the independent terms
=(-9m -6m - 6m - 6m - 18 m) + (12+12+8+24+8)
= - 45m + 64.
Thus, the expression is -45m + 64.
