Answer: the polygon has 20 sides.

Step-by-step explanation:

The formula for determining the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.

if the sum of the measures of the interior angles is 3960

degrees. This means that

(n - 2) × 180 = 3960

Expanding the brackets by applying the distributive property, it becomes

180n - 360 = 3960

180n = 3960 - 360

180n = 3600

Dividing both sides by 180, it becomes

n = 3600/180

n = 20

Simplify 9x^8 divided by 12x^5.

Dmitry_Shevchenko [17]

Ok, so rembmer some basica exponential rules and some fraction rules

(ab)/(cd)=(a/c)(b/d)
and
$\frac{x^n}{x^m} =x^{n_m}$

so
$\frac{9x^8}{12x^5}=( \frac{9}{12} )( \frac{x^8}{x^5} )=( \frac{3}{4} )( x^{8-5} )= ( \frac{3}{4} )( x^{3} )= \frac{3x^3}{4}$
