Find C on the directed line segment AB with A(- 2, 6) and B(8, 1) such that AC:CB = 2:3

Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.
