The center of an ellipse is located at (0,0). One focus Which equation represents the ellipse? is located at (12,0), and one directrix is at x=14(1)/(12). (x^(2))/(13^(2))+(y^(2))/(5^(2))=1 (x^(2))/(13^(2)+(y^(2))/(12^(2))=1 (x^(2))/(14^(2))+ (y^(2))/(5^(2))=1 and return (x^(2))/(14^(2))+(y^(2))/(13^(2))=1 Mark this
