Answer:

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here the sum is 2520, thus

180° (n - 2) = 2520 ( divide both sides by 180 )

n - 2 = 14 ( add 2 to both sides )

n = 16

The polygon has 16 sides.

I need the solution and the work for it... for each of the multiple choices.

Vlad1618 [11]

For this case we have the following equation:

$x ^ 3 = 375$

We must find the value of "x":

We apply cube root on both sides of the equation to eliminate the exponent:

$x = \sqrt [3] {375}$

We can write 375 as $5 ^ 3 * 3$

So:

$x = \sqrt [3] {5 ^ 3 * 3}\\x = 5 \sqrt [3] {3}$

Then, the correct options are:

$x = \sqrt [3] {375}\\x = 5 \sqrt [3] {3}$

$\sf \longmapsto \: 2x + 21 = 3$

$\sf \longmapsto2x = 3 - 21$

$\sf \longmapsto2x = - 18$

$\sf \longmapsto \: x = \frac{ - 18}{2}$

$\sf \longmapsto x = - 9$

Whats the answer to this problem

The answer would be to the right since after you factor the equation out the 9 is positive
