The correct answer is that AC = 4x - 2 or 2 (2x - 1)
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
AD = 6x + 10
CD = 2x + 12
2. Let's find the length of AC
AC = AD - CD
Replacing with the real values:
AC = (6x + 10) - (2x + 12)
AC = 6x + 10 - 2x - 12
AC = 6x - 2x + 10 - 12
AC = 4x - 2 or 2 (2x - 1)
