Answer 3

To simplify the expression -9(4-b)+3(-3b-3)-6(-9+b), you can follow these steps:

1. Distribute the constants inside the parentheses: -9 * 4 + 9 * b + 3 * (-3b) + 3 * (-3) - 6 * (-9) + 6 * b

2. Multiply the constants: -36 + 9b - 9b - 9 - 54 + 6b

3. Combine like terms: (9b - 9b) cancels out, and (6b - 0b) equals 6b, so the expression becomes:

-36 - 9 - 54 + 6b

4. Add and subtract the numbers: (-36 - 9 - 54) equals -99, so the simplified expression is:

-99 + 6b

So, the simplified expression is -99 + 6b.
