Simplify the expression:

Question

-8(-7r-10)+5r

Answer 1

To simplify the expression \(-8(-7r-10)+5r\), we start with distributing \(-8\) to both terms inside the parentheses.

1. Distribute \(-8\): \[ -8(-7r) - 8(-10) = 56r + 80 \]

2. Now, we add the \(5r\) to this result: \[ 56r + 80 + 5r \]

3. Combine the \(r\) terms: \[ 56r + 5r = 61r \]

4. Therefore, the expression simplifies to: \[ 61r + 80 \]

Thus, the simplified expression is: \[ \boxed{61r + 80} \]
