compute a+b+c+d-e from the diagram above thanks!
I know i shouldn't be overthinking this, but I'm still not verysure. Does this ask me to actually draw out vectors? or do i justfollow some sort of law to find an answer? help very muchappreciated!

I NEED HELP WITH ANSWERS TO (C) AND (E) ONLY. THANK YOU
1. What is the area of the region bounded by the curves y = 2x^2 - 7 and y = 2/x between x=1 and x=3?
The answer I get, both by calculator and by hand, is 2ln(3) - 10/3. According to the test, it is 4ln(2) - 2ln(3) + 8. Even my calculator doesn't think that is equivalent.
This is from a Straighter Line test. They have been known to have some errors on their tests. If this is one of them, please inform me.
2. The second question is one I never really learned the way to do. I know how to get four points from it. But the rest of my methods seem convoluted. It is: what is the area of the parallelogram whose edges are the lines y = - 1/2 * x - 1, y = x + 2, y = - 1/2 x + 2, and y = x - 5/2. What is the way to do this? Or, is there a particularly efficient and quick way to do it?
These two questions are from Calculus I. I mention this in case it helps to contextualize what methods you would recommend I answer this with. The Straighter Line course I am taking is very bad in regards to presenting all the information you need to know--if fact, it doesn't--so I have had to pick up quite a few things on the side myself. I may not have learned what I am supposed to do with some of these situations. But, I think the first of the two questions may be the result of an error on the part of Straighter LIne.
Ah, so, thank you for any answers.
I'm having trouble understanding on how to setup an equation for an ellipse. Thanks for any help
