This is to say that the sum of the radii $underbrace_r_1+underbrace_r_2=underbrace10_2a,$
according to the definition on Wolfram Mathworld http://mathworld.wolfram.com/Ellipse.html
Oh thanks you very much.ðÂÂÂð»ðÂÂÂð»

Hint: You can see it as an ellipse with focuses $(-1,0)$ and $(7,0)$ and $a=10/2$.
Excuse me, can you tell why focuses (1,0) and (7,0)? Is it definition?
