Answer:
900
Step-by-step explanation:
(n – 2)180 where n is the number of sides
since this is a 7 sided polygon
(7-2) * 180
5 * 180
900
The answer is 4. The question is what is 2+2?
Answer is A
144 + 12y + y^2
if perfect square should be
144 + 24y + y^2
The length is 7 and the width is 3
I think the answer should be 12.
