The first one I think it is D) 8
The third one I think is 7.2.
The fourth one I think is B) (2,1)
The last one I think is either B or C.
The second one I don't know at all. Sorry. Please help.
+168 1 is B because if you count the squares the scale factor is 3
2 is c (correct me if im wrong)
i think learning scale factor will help you in this topic.
