As the exterior angles always add up to 360, you can find the number of sides by dividing 360 by the measure of your exterior angle, 30. This gives you 360/30=12, meaning your polygon has 12 sides.

Answer:
8n³ + 10n² - 13n - 15
Step-by-step explanation:
Distribute the factors by multiplying each term in the first factor by each term in the second factor, that is
4n(2n² + 5n + 3) - 5(2n² + 5n + 3) ← distribute both parenthesis
= 8n³ + 20n² + 12n - 10n² - 25n - 15 ← collect like terms
= 8n³ + 10n² - 13n - 15
1 cubic foot = 7.48 gallons
hence
unit conversion
3000 x 7.48 =22440
Answer:
Option C 
Step-by-step explanation:
we know that
The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises
so
we have
substitute
