So for this, we will be using proportions. In this case, our proportion will be 
Firstly, cross-multiply: 36 = 3x
Next, divide both sides by 3 and your answer will be: 12 = x
Answer: A
Step-by-step explanation:
To solve this problem, think of a coordinate plane. Look at the first x and y on the table. The x is zero and the y is 8. Now look at the answers. For x to be zero while y has a value would mean that it would have a y-intercept of 8. The only answer that has a y-intercept of that value is A.
To prove that A is the correct problem, try to do slope intercept with it. The slope is 9, so the y increases by 9 and the x increases by 1. 8 + 9 is 17, which is the second y. 0 + 1 is 1, which is the second x. So A must be the correct answer.
They get easier once you keep doing them, It took me a little while to learn.

−2 − (−6)
the minus negative becomes +
-2 +6
subtract the smaller from the larger and take the sign of the larger
6-2 =4
the sign of the larger is +
+4
Answer: +4
Answer:
D
Step-by-step explanation:
r=8/2=4 ( the radius)
S=2*pi*r(r+h)= 2*3.14*4*(4+8)=2*3.14*4*12=96*3.14=301.44
so D is the closest
