You welc

Answer 6

So, first you need to find the value of x. Then you'll need to plug x in to show that the parallel sides are equal

Answer 7

AD=BC
AB=DC

Answer 8

We can just use the upper one, so 3x+23 = 3-x
Can you solve for x?

Answer 9

Yes I can

Answer 10

What does x equal

Answer 11

-5

Answer 12

it would be -5. you will get the answer by making the opposite sides equal.
ab=cd and bc=ad 😁 yw

Answer 13

Thanks

Answer 14

So, now that you got x, you have to plug that into the 4 expressions, to show that there are 2 pairs of equal lengths
