Can someone help me with this?

Step-by-step explanation:

The formula for the volume of a sphere is V = 4/3 πr³.

Given

Volume (v) = 57ft³

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

$57 = \frac{4}{3} \times 3.14 \times {r}^{3}$

$57 = \frac{12.56}{3} \times {r}^{3}$

$57 = 4.19 \times {r}^{3}$

${r}^{3} = \frac{57}{4.19}$

${r}^{3} = 13.6$

$r = \sqrt[3]{13.6}$

Therefore r = 2.4 ft

I gave my answers by rounding off. so if you don't round off then it's answer is 2.3 ft

Simplify completely 12 times x to the third power minus 4 times x to the 2nd power plus 8 times x all over negative 2 times x. (

jok3333 [9.3K]

So we want to simplify
$\frac{12 {x}^{3} - 4 {x }^{2} + 8x }{ - 2x}$
We split the numerators,

$= \frac{12 {x}^{?3} }{ - 2x} - \frac{4x {}^{2} }{ - 2x} + \frac{8x}{ - 2x}$
$= - 6 {x}^{2} + 2x - 4$
The correct answer is B.
