Answer:
38
Step-by-step explanation:
If line y bisects AC at B
Bisect means divide a line into two equal parts.
Therefore, AB=BC
where, AB = 4-5x and BC = 2x+25
4-5x = 2x+25
-7x = 21
x = -3
Thus,
AB = 4-5x
= 4-5(-3)
= 19
BC = 2x+25
= 2(-3) + 25
= 19
AC = AB+BC
= 19 + 19
= 38
Hence, The length of AC is 38
