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: \[ 108m - 9 \]
