Answer:
x > 12
Step-by-step explanation:
9x>108
x> 108/9
x > 12
You haven't shared all of the question, so I'll guess that you want to find "how fast is the area of the sphere increasing?"
Area of a sphere = 4*pi*r^2
Rate of change of area of a sphere with respect to radius r:
dA/dr = 8*pi*r*(dr/dt)
Here, that would come out to
dA/dr = 8*pi*r*(2 inches / sec)
If you meant, "how fast is the volume of the sphere increasing?" you'd need to use a different equation:
V = (4/3)*pi)*r^3
and go through a similar process.

I hope this helps you
1)
f (4)=5.4+9
f (4)=29
2)
f (4)=5.4-9
f (4)=11
