Question

E is the midpoint of df. de =6x and ef=3x+6. find de, ef, and df.

Answer 1

Since E is a midpoint, we can set de and ef equal to each other to find the value of x. 

6x = 3x + 6
3x = 6
x = 2

Then we can plug in x=2 and find that both de and ef are 12. Then since E is the midpoint of df, we can add de and ef to find the value of df. 

12 + 12 = 24
