Question

What happens to the value?

Answer 1

D.) c is multiplied by 4

Explanation:

`c = (8a^3)/(b)`

If a is doubled, it becomes 2a. If b is doubled, it becomes 2b. Now we replace a with 2a and b with 2b and simplify.

`c = (8(2a)^3)/(2b)`

`c = (8 * 8a^3)/(2b)`

`c = (4 * 8a^3)/(b)`

`c = 4 * (8a^3)/(b)`

Answer: D.) c is multiplied by 4
