Final answer:
To find the values of BD, ED, CA, and AE, substitute the given values into the equations.
Step-by-step explanation:
To find the values of BD, ED, CA, and AE, we need to understand the given equations:
BD = 3x - 7
CA = x + 5
First, we substitute the value of BD and CA in the equations:
ED = BD = 3x - 7
AE = CA = x + 5
Therefore, the correct option is A) BD = 3x - 7, ED = 3x - 7, CA = x + 5, AE = x + 5.
