Hurry pleaseee I'm in a quiz The unshaded trapezoid is the image of the shaded trapezoid after a series or transformation (IMAGE ABOVE)

What is the value of x?
3
9
12
18​

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Iagree that is the answer to the question
