Rewrite in simplest terms: minus, 8, left parenthesis, 10, r, plus, 10, r, minus, 6, right parenthesis, minus, 3, r−8(10r+10r−6)−3r

Answer 1

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:

\(-163r + 48\).
