1= 65
2= 115
3= 65
5= 75
7=75
8=105
-4 + 3(x+4) = -4 + 5x
-4 + 3x + 12 = -4 + 5x
8 + 3x = -4 + 5x
(8+4)= (5x - 3x)
12 = 2x
So x = 6.
The standard form of an ellipse with horizontal major axis as in this problem is:

where
"a" is greater than "b"
the major axis is length of 16 which means a = 8 and the minor axis length is 8 which means b = 4
the equation then is: Choice B
Answer:
7200
