Question

Rewrite in simplest terms: minus, 9, left parenthesis, minus, 8, m, minus, 5, m, plus, 1, right parenthesis, minus, 9, m−9(−8m−5m+1)−9m

Answer 1

Let's simplify the expression step by step.

We start with:
\[
-9(-8m - 5m + 1) - 9m
\]

First, combine the terms inside the parentheses:
\[
-8m - 5m + 1 = -13m + 1
\]

Now substitute this back into the expression:
\[
-9(-13m + 1) - 9m
\]

Next, distribute \(-9\) into the parentheses:
\[
9 \cdot 13m - 9 \cdot 1 - 9m = 117m - 9 - 9m
\]

Now combine the \(m\) terms:
\[
117m - 9m = 108m
\]

So, the simplified expression is:
\[
108m - 9
\]

Thus, the final answer is:
\[
108m - 9
\]
