Answer:
A. 6
Step-by-step explanation:
Taking into account the figure, we can write the following equation
BD = BC + CD
x + 2 = 2 + (2x - 6)
Then, we can solve the equation for x
x + 2 = 2 + 2x - 6
x + 2 = 2x - 4
x + 2 + 4 = 2x - 4 + 4
x + 6 = 2x
x + 6 - x = 2x - x
6 = x
Therefore, the value of x is A. 6
