Ling listed all of the factors of a mystery number: 1,2,4,8,16,32 what is the mystery number?

Asap (i need to finish this quick) graph complete the sequence of transformations that produces △x'y'z' from △xyz. a clockwise rotation ° about the origin followed by a translation units to the right and 6 units down produces δx'y'z' from δxyz.
