Step-by-step explanation:
Simple. Just add/subtract each term. 4n-2n=2n. 8m+7m=15m.
This is very basic stuff.
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.
Answer:
A is given by:
Step-by-step explanation:
The base length of the triangle is 4 units shorter than the height.
This means that 
So
The expression for A in terms of h only was given above.
