    4. If one pair of opposite sides of a quadrilateral is both parallel and congruent, then the quadrilateral is a parallelogram. So, 3x+1 = 6x-4 and x = 5/3.

    4x-1=x+38 (if I saw the numbers right. They are very small)

    Number 8 I don't think so but I can't see it very well. only thing I can see is that one diagonal is bisected.

    x = 5/3. There is no y variable. See original post above.

    Agree with Mert on #8. The quad is not a parallelogram.

    x =13 on #6 because one pair of opposite sides is both congruent and parallel.
