Answer 3

To simplify the expression −8(3−a)+4(−3a−3)−6(−9+a), you can follow these steps:

1. Distribute the coefficients within each parenthesis: -8 * 3 + 8 * a + 4 * (-3a) + 4 * (-3) + 6 * 9 - 6 * a

2. Multiply the coefficients with the values inside the parentheses: -24 + 8a - 12a - 12 + 54 - 6a

3. Combine like terms: (8a - 12a - 6a) + (-24 - 12) + 54

4. Simplify the coefficients of the variable 'a': -10a + 18

5. Add the constants: -10a + 18

So, the simplified expression is -10a + 18.
