#7 i dont understand can some one do it and explain

Answer: The answer is yes
Step-by-step explanation:
A parallelogram states that both opposite sides are equal.
So look at line AB, plug in 5 for x and that gives you 27.
Now look at line DC, and plus in 5 for x, and that gives you 27 as well.
Now, do the same for AD, and BC.
Plug in 4 for AD and that gives you 20.
Plug in 4 for BC and that gives you 20 as well.
Hope this helps!
