D=4n-2, d+2=4n-2+2, d+2=4n
(d+2)/4=(4n)/4, 1/4d+1/2=n
n=1/4n+1/2

size 3=
n=1/4*3/1=3/4, 3/4+1/2=5/4=1 1/4
size 3=1 1/4

size 6=
n=1/4*6/1=6/4, 6/4+1/2=8/4=2

WILL MARK BRAINLEST PLS HELP
Rudiy27

Answer:

None

Step-by-step explanation:

The center of the ellipse is at  (2,  4)

The length of the x axis is  a=  (8-2) =6

The length of the y axis is b=(16-4) = 12

The formula for an ellipse is

(x-h) ^2       (y-k)^2

----------- + -------------- = 1^2

a^2              b^2

where (h,k) is the center

and a and b are the  lengths of the major and minor axes

(x-2) ^2       (y-4)^2

----------- + -------------- = 1

6^2              12^2

 none of your choices have b>a  and for the ellipse to be vertical b>a
