Can anyone answer me i believe the answer is d am i correctit is asking how to prove the figure is a parallelogram.

I think the answer is B because to prove that a parallelogram is a parallelogram is well.. if the sides are parallel

hope this helps!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
