Question

−8(3−b)+3(−2b−2)−7(−9+b).

Answer 1

Ответ:

Пошаговое объяснение:

−8(3−b)+3(−2b−2)−7(−9+b) = -24 + 8b - 6b - 6 + 63 - 7b = 33 - 5b

Answer 2

To simplify the expression $-8(3-b) + 3(-2b-2) - 7(-9+b)$, you can distribute and combine like terms:

1. Distribute the numbers outside the parentheses:

   $$\begin{align*} -8(3-b) & = -24 + 8b \\ 3(-2b-2) & = -6b - 6 \\ -7(-9+b) & = 63 - 7b \end{align*}$$

2. Substitute these results back into the original expression:

   $$(-24 + 8b) + (-6b - 6) + (63 - 7b)$$

3. Combine like terms:

   $$-24 - 6 - 63 + 8b - 6b - 7b$$

4. Combine constants and like terms:

   $$-93 + (-5b)$$

So, the simplified expression is $-5b - 93$.
