Answer:
AC = 22
Step-by-step explanation:
Given that B is the midpoint of AC , then AB = BC , that is
2x + 1 = 5x - 14 ( subtract 2x from both sides )
1 = 3x - 14 ( add 14 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
Thus
AC = AB + BC = 2x + 1 + 5x - 14 = 7x - 13 = 7(5) - 13 = 35 - 13 = 22
