Answer 1

To simplify the expression −4(7b+3)+24b−8, follow the order of operations (PEMDAS/BODMAS):

First, distribute the multiplication inside the parentheses:

−4 * 7b = −28b
−4 * 3 = −12

So we get:
−28b − 12 + 24b − 8

Now, combine like terms:

−28b + 24b = −4b
−12 − 8 = −20

So the simplified expression is:

−4b − 20

Therefore, the correct answer is:

−4b − 20
