I’m pretty sure it is 66 since the base would be congruent to the top so plug in 7 into 10u-4 and u get 66!! (You plug in 7 since u=7)
The first two steps would be A
The equation of an ellipse is x²/a² + y²/b² =1
a being the distance between the center & x intercept =7
b being the distance between the center & y intercept =5
Hence the equation of this ellipse is:
x²/49 + y²/25 =1
No. I can’t. Just wanting to get some points man, 5 would be nice.
