Answer:
m》9
Step-by-step explanation:
-1/3 m 《-3
Multiply both sides by -3
(Don't forget to flip the inequality
m》9
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 15*ln(m)-6*ln(n)
Answer: x=-2
Step-by-step explanation:
First subtract 4 from both sides
Sqrt(x+3)=1
Then square both sides
X+3=1
Then subtract 3
X=-2
