(a + b)^3 = a^3 + 3a^2b + 3ab^2+ b^3
(a +(- b))^3 = (a-b)^2 = a^3 - 3a^2b + 3ab^2- b^3
My calculator says bad expression.

Answer:
- Q11 - 12 sides
- Q12 - 10 sides
Step-by-step explanation:
<u>Use the formula for sum of interior angles of a regular polygon:</u>
<u>Each angle A measures:</u>
- S/n = 180(n - 2)/n
- A = 180(n - 2)n
- An = 180n - 360
- (180 - A)n = 360
- n = 360/(180 - A)
<h3>Question 11</h3>
<u>Each angle is 150, then finding n:</u>
- n = 360/(180 - 150)
- n = 360/30
- n = 12
<h3>Question 12</h3>
<u>Each angle is 144, find n:</u>
- n = 360/(180 - 144)
- n = 360/36
- n = 10
