Answer:
Step-by-step explanation:
N is 3 bc #of terms minus 1
Exponents go from 3>2>x>none
Can be factored using binomial theorem
-16 + (-22) - 14
First, simplify your brackets. / Your problem should look like:
Second, subtract -16 - 22 - 14 to get -52. / Your problem should look like:

Answer:
-52
I think the answer is c for the graph
Area = 267
perimeter = 72
area- solve for the area of the 18 by 10 section, then the area of the 7 by 21 section. once you have those, determined the size of the shared area between those two and subtract from one of them.
perimeter- just add
The answer is 75 % you just have to divide 84 and 112 and u get 75%
