Simplify - 4(7b + 3) + 24b - 8
A. - 4b - 20
B. - 4b - 20
C. 4b + 20
D. - 4b + 20
To simplify the expression - 4(7b + 3) + 24b - 8, we can begin by expanding the parentheses:
- 4(7b + 3) + 24b - 8
= - 4 * 7b - 4 * 3 + 24b - 8
= -28b - 12 + 24b - 8
Next, we can combine like terms:
= (-28b + 24b) + (-12 - 8)
= -4b - 20
So, the simplified expression is -4b - 20.
Therefore, the correct answer is A. -4b - 20.
