Can someone help me with this?

Answer:
x = 9
A(lol,brainly wont let me post this)F = 19
Step-by-step explanation:
see image. Since F is the midpoint, both halves of the segment must have the same measure.
If AhalfF is 2x+1, then the other half of AD must also be 2x+1.
We were given the length of the whole thing as well, so we can set up an equation to solve. See image.
