There isn’t enough information to find the answer because the first number is telling how many people visited to local fair last month.
If you were to compare the number of people that visited the local fair last month and the number of people that visited the museum this month then the answer would be 1359 but, it’s not asking for that. This is why you cannot solve this problem
You would set your equation up like this:
f(x)*g(x)
(3x^2)*(x+2) or 3x^2(x+2)
3x^3+6x^2
Your answer would be C
Multiply 4 or 
on both sides to get c by itself
c ≤ 16
C is correct because the first point is on 0
<2 + <5 = 180 this is a straight line
<2 + 150= 180
subtract 150 from each side
<2 = 30
<2 + <3 + <4 = 180 a triangle is 180 degrees
30 + <3 + 70 = 180
100 + <3 = 180
<3 = 80
