Answer 2

Let's solve the expressions step by step:

1. -16 * (2 * 6 - 7)

First, perform the operation inside the parentheses:

2 * 6 - 7 = 12 - 7 = 5

Now, substitute this value back into the expression:

-16 * 5 = -80

So, -16 * (2 * 6 - 7) = -80

2. -0.4 * (3 * 7 + 4)

First, perform the operation inside the parentheses:

3 * 7 + 4 = 21 + 4 = 25

Now, substitute this value back into the expression:

-0.4 * 25 = -10

So, -0.4 * (3 * 7 + 4) = -10
