Ineed on 5-6 because i just don’t understand it

5. reduction 6.enlargement

Step-by-step explanation:

if the scale factor is greater than one (for example) 2 then it will enlarge, but if the scale factor is less than one, it is reduced.

An in #5, from A to B the rectangle goes from bigger (A) to smaller (B) so it must have a smaller scale factor in order to reduce ,and in #6 A is smaller and B is bigger which goes back to the concept of it must have a bigger scale factor in order for it to enlarge. But all in all you can see in #5 A. is the bigger rectangle so in order to become the rectangle in B. it must reduce.
