Answer:
8 : 1
Step-by-step explanation:
Given ratio of sides = a : b, then
ratio of area = a² : b²
ratio of volumes = a³ : b³
Given
ratio of areas = 384 : 96 = 4 : 1 ← in simplest form, then
ratio of sides =
:
= 2 : 1
Hence
ratio of volumes = 2³ : 1³ = 8 : 1
<span>Because you have changed the sign of the divisor as part of setting up the synthetic division.
The whole point of changing the divisor's sign is allow addition (which is easier) instead of subtraction.</span>
