Question 794910:
The Equation of an Ellipse is shown below.
(x+2)^2/100 + (y+7)^2/36 =1
What is the length of its major axis?
a^2= 100
sqrt of 100=10
10=semimajor axis
10x2= 20.
20=major axis length?

I think I'm right but I'm not sure.

You can put this solution on YOUR website!
(x+2)^2/100 + (y+7)^2/36 =1
What is the length of its major axis?
a^2= 100
sqrt of 100=10
10=semimajor axis
10x2= 20.
20=major axis length?

I think I'm right but I'm not sure.
---------------
It is 20.
