The worlds Smallest plane has a length of 12 feet the worlds largest plane has a length of 302 feet write an absolute value equation that represents the minimum and maximum lengths use X to represent the lengths.

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.
