Answer:
Explanations:
Let the coordinates of the focus(-3, 0) be:
x₁ = -3, y₁ = 0
Let the coordinates of the focus(3, 0) be:
x₂ = 3, y ₂ = 0
Let the coordinates of point(7, 0) be:
x₃ = 7, y₃ = 0
Let the distance between the Focus(-3, 0) and (7, 0) be d₁
Let the distance between the Focus (3, 0) and (7, 0) be d₂
