Every added angle to a polygon adds another 180 degrees to the sum of the angles. The starting point is 180 degrees for a triangle (n=3). So the general formula is 180*(n-2). Fill in n=3 to test if 180 comes out, it does!!

Answer:
d. x²+2
Step-by-step explanation:
x²+2x+1-2x-2+3 = x²+2
Linear equations are 2a + 3b = 82 and a + b = 38
A = 32
B = 6
