Answer:

2x² - 3x - 8

Step-by-step explanation:

note that (f - g )(x) = f(x) - g(x)

= 2x² - 5 - (3x + 3) = 2x² - 5 - 3x - 3 = 2x² - 3x - 8

Answer:

The radius of the sphere is $6\ cm$

Step-by-step explanation:

we know that

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

In this problem we have

$V=288\pi\ cm^{3}$

substitute and solve for r

$288\pi=\frac{4}{3}\pi r^{3}$

simplify

$288*3/4=r^{3}$

$r^{3}=216$

$r=6\ cm$
