The answer is 24 sides
because the total amount of the exterior angles of a polygon is 360.
so if each exterior angle has a measure of 15:
This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying . This is the second line. Then, you could take the square of the 
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
Just squish the two equations into one equation and idk im just typing this because i apparently need a twenty character long answer
18 2/5 = 92/5 = 18.4 as a decimal;
