Question

Help please my teacher isn't the greatest.

Answer 1

9.5 and im sorry ur teacher is bad

Answer 2

x = 9.5

Explanation:

We see that the entire length of DF is equal to 34. That means segment DE and segment EF must combine to equal 34:

3x - 6 + x + 2 = 34

4x - 6 + 2 = 34

4x - 4 = 34

4x = 38

x = 9.5
