Answer:
1) if we plug 2 in x, f (2)/(2-2)=100/0=undefined
2)ofcourse, when u plug -2 it makes it 0, f (-2)=0
3)the remainder being constant implies it is divisible by (x-1), 2x^2 (x-1)+4 (x-1), so ax^2=2x^2, a=2
7-12(3+b)=31
7-36+12b=31
-29+12b=31
12b=31+29
12b=60
b=5
Interior angles sum: 180(3-2) = 180
180 - (76 + 59) = 45
Your answer: 45
18 x 4 = 72
(9 x 2) x 4 = 72
9 x (2 x 4) = 72
