Answer:

6m - 6

Step-by-step explanation:

9m + 2 - (3m + 8) = 9m + 2 -3m -8

= 9m - 3m + 2 - 8

= 6m - 6

when you open the brackets, -(+3m) = -3m because when a positive sign times a negative sign, you get a negative sign. so, same thing for -(+8) = -8

The minimum and maximum distances from a focus to a point on an ellipse occur when that point on the ellipse is an endpoint of t
Sauron [17]
The answer is True.

Explanation:
Let a =  major axis
Let b = minor axis
Let c =  focal length.

Consider the right focus, located a distance c from the center of the ellipse (at the origin).
From the right focus to the right point on the major axis is equal to a-c. This is the minimum distance.
From the right focus to the left point on the major axis is equal to a+c. This is the maximum distance.
