Step-by-step explanation:
The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
the answer is B because if you.........................................................................................................................................
First of all, we have to observe that the expression makes sense only if
otherwise, you'd have zero denominators, which are not allowed. So, assuming , let's sum the two fractions at the left hand side:
Again, since we're assuming , we can multiply both sides by to get
This equation has solutions and , but we can only accept the first, since 1 is a forbidden value.
So, the only solutions to this equation is

2^x * 2 = 15
2^x= 15/2
2^x = 7,5
x = log 2 (7,5)
