Answer:
D.) c is multiplied by 4
Step-by-step explanation:
[tex] c = \dfrac{8a^3}{b} [/tex]
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.
[tex] c = \dfrac{8(2a)^3}{2b} [/tex]
[tex] c = \dfrac{8 \times 8a^3}{2b} [/tex]
[tex] c = \dfrac{4 \times 8a^3}{b} [/tex]
[tex] c = 4 \times \dfrac{8a^3}{b} [/tex]
