The variable a cannot be zero because that would make -9a = zero and 8 divided by zero is indeterminate.
Answer:
We have:
7 + 4 = 11;
11 - 7 = 4;
11 x 2 = 22;
4 x 4 = 16;
22 - 16 = 6;
Finally, 8 x 6 = 48;
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
Substitute the given values into the expression
b²(a - 2c)
= (- 4)²(3 - 2(- 1))
= 16(3 + 2)
= 16 × 5
= 80
