To simplify the expression \(-8(10r + 10r - 6) - 3r\), follow these steps:
1. Combine like terms inside the parentheses:
- \(10r + 10r = 20r\)
- So, \(10r + 10r - 6 = 20r - 6\).
2. Substitute back into the expression:
- Now the expression is \(-8(20r - 6) - 3r\).
3. Distribute \(-8\):
- \(-8 \times 20r = -160r\)
- \(-8 \times -6 = 48\).
4. So, it becomes \(-160r + 48 - 3r\).
5. Combine like terms:
- \(-160r - 3r = -163r\).
Thus, the simplified expression is:
\(-163r + 48\).
