help on 4, 6, 8
Find the values of X and Y for which ABCD must be a parallelagram.

Answer 1

Thanks

Answer 2

3x+1=6x-4

Answer 3

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.

Answer 4

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

Answer 5

so then X and Y would be for number 4?

Answer 6

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.

Answer 7

ill re send it

Answer 8
