Answer:
44 units
Step-by-step explanation:
We know that B is the midpoint of AC, so by definition, AB = BC. Thus, set the two expressions equal and solve for x:
AB = BC
4x + 14 = x + 20
3x = 6
x = 2
Given that x = 2, plug this into the expression for AB and BC and add them to get AC:
AC = AB + BC = 4 * 2 + 14 + 2 + 20 = 44
Hence, AC is 44 units.
Hope this helps!
