Answer:
D) 10 units
Step-by-step explanation:
Opposite sides of a parallelogram are congruent.
__
setup
The relation between opposite sides tells you ...
BC = AD
2x = x +5
solution
x = 5 . . . . . . . subtract x from both sides of the equation
We want the length of AD, which is ...
AD = x +5 = 5 +5
AD = 10

Additional comment
Often, it seems like the question is answered once the value of x is found. Here, finding the value of x is an intermediate step. The value of x is needed in order to be able to answer the question about the value of an expression involving x.
Answer:
10
Step-by-step explanation:
→ Equate both sides of the parallelogram as they are equal
2x = x + 5
→ Solve
x = 5
→ Resubstitute for the length AD
5 + 5 = 10
