Answer 8

okay, it doesn't look like the symmetric curves I am looking at.

Answer 9

The lesson that I had didn't tell us how to integrate them.

Answer 10

Can you not see how you can compute the area under the curve?

Draw rectangles and triangles on top of the rectangles to fit the curve.

Answer 12

okay

Answer 14

So there's your answer.
