Answer:
A
B
E
Step-by-step explanation:
If you find what 11 squared is: 121
All number greater than or equal to 121 will be solutions.
Well, the amount of degrees is 1,980, so plug that in so that the equation is 1980 = (n-2)180. Then, do order of operations. Divide 1980/180, which is 11. Then, just add 2. So, the polygon has 13 sides.
Answer:
x=4
Step-by-step explanation:
13x+1 = 11x+9
13x-11x = 9-1
2x = 8
x = 4
Divide both sides by -7, and flip the sign: 3 > c
