An octagon has a perimeter of 28 units. What is the perimeter of the image of the octagon after the translation
(x, y) —> (x-7,y+6), a rotation 90° clockwise, and a reflection across the y-axis?

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.

What’s your question.
