Answer:
<h2><u><em>
nonagon, 9 sides</em></u></h2>
Step-by-step explanation:
the interior angles is 360 - 220 = 140°
it's a<u><em> nonagon, 9 sides</em></u>
<u><em></em></u>
(3s^13)(9s^-5) is simply a matter of multiplication.
First, multiply the coefficients, or the numbers in front of the s. In this case, 3s x 9s = 27s.
When multiplying exponents, you simply add them, so the next step is 13-5 or 8. Therefore your answer is 27s^8
