Easy, 

plotting it on a graph...

(-2,3) (4,3) (4,-4) (-2,-4)

Now, if done correctly, when you count the "points" it should be lengthwise

6 units, and width would be 7

6*7=42

The Area is 42 units squared.

Question 2:
The answer is 21
The two angles are vertically opposite, which makes them equal and also means we can make an equation:
4x - 4 = 3x + 17
- 3x
x - 4 = 14
+ 4
x = 21

Question 3:
The answer is 23
Again, the angles are vertically opposite, so we can make them equal each other:
5x - 53 = 3x - 7
- 3x
2x - 53 = -7
+ 53
2x = 46
÷ 2
x = 23

I hope this helps!

How far apart are the foci of an ellipse with a major axis of 20 feet and a minor axis of 14 feet?
omeli [17]
The solution for this question is simple. First we need to divide both numbers by 2 which will give us 10 and 7. This is the equation x^2/10^2 + y^2/7^2 = 1sqrt(100-49) = 7.14 (the answer do not have a perfect square root)
Foci are 14.28 units apart
