Question

-8(2z - 7c) use z = 5 and c = 2

Answer 1

Answer is 32

Step 1. Solve inside the parentheses so 2x5= 10 and 7x2=14 then you have -8(10-14)

Step 2. Distribute -8 so -8x10= -80 and -8x14= -112 = -80- -112

Step 3. Subtract totals: -80- -112 = 32 it’s a positive because of the two negatives being subtracted together

Answer 2

Answer:

The answer is

-8(2×5-7×2)

=-8(10-14).

= -8(-4)

= 32.
