Which of the following statements about an ellipse are true? an ellipse is similar to a circle. an ellipse has a radius. an ellipse has two foci. the sum of the distances from each focus to any point on the ellipse will always be the same. an ellipse has a diameter.

A Circle is an Ellipse, where both foci are at the same point .In other words, a circle is a "special case" of an ellipse .An ellipse is the set of all points on a plane whose distance from two fixed points F and G add up to a constant. In an ellipse, there are two radius measures, one horizontally along the x-axis, the other vertically along the y-axis.For  a circle both these have the same value.

The statements true for an Ellipse are:

An ellipse is similar to a circle.

An ellipse has two foci.

The sum of the distances from each focus to any point on the ellipse will always be the same.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

5x+10 is the correct one

hope this
