Answer:

The answer to your question is letter B. 8

Step-by-step explanation:

Data

Major axis length = 12 = 2a

red line = 4

blue line = ?

Process

In an ellipse, the distance from the focus to a point is equal to the major axis.

                     2a = PF + PF'

Substitution

                     12 = PF + 4

Solve for PF

                      PF = 12 - 4

Simplification and result

                      PF = 8

Answer:

8
