Answer:
12
Step-by-step explanation:
1) A graph is linear when the line on a graph is a straight line with no curves.
2) A proportional graph means that as x increases, y increases and when x decreases, y decreases and their ratio always stays the same.
3) (I don't know what type of equation you mean but this is my guess)
Division is the last step of an equation.
Hope you don’t mind reading handwriting. I named two of the angles to make the explanation easier
4, 16
-1, 1
3, 9
12, 144
16, 256
The rule is y=x^2. If you square all the numbers on the x side, you will get the numbers on the y side. 4 times 4 = 16. -1 times -1 =1. 3 times 3 =9, and so on.
60x to the 4th power +165x to the 3rd +39x squared - 132x - 30 i think
