Answer:
x = 0 x= -9
Step-by-step explanation:
x^2 + 18x = 9x
Subtract 9x from each side
x^2 + 18x-9x = 9x-9x
x^2 +9x = 0
Factor x from the left hand side
x(x+9) =0
Using the zero product property
x=0 x+9 = 0
x =0 x+9-9 = 0-9
x = 0 x= -9

Answer:
32π is the volume of the larger sphere
Step-by-step explanation:
The volume of a sphere is V = 4/3πr³. The smaller sphere is V = 4π. This means r³ divided by 3 was 1. So r³ = 3. For the larger sphere, substitute r = 2r into the volume formula.
V = 4/3πr³
V = 4/3π(2r)³
V = 4/3π8r³
We know from the previous problem that r³ = 3.
So the volume formula simplifies to V = 4π(8) = 32π
