Simplify the expression. (–9m + 12) –6m + 12 –6m + 8 –6m + 24 –18m + 8 description

-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.

if x = 1, then the answer is 3.5
