Best ResponseYou've already chosen the best response.1Oh, and I understand that none of the answer options for question 4 are correct. If I don't get that question right, I'll have to Email my teacher about it. This happens a lot more than it should.

Best ResponseYou've already chosen the best response.1Would it be 4 : 9, since the scale factor is 2/3 and I have to square that?

Best ResponseYou've already chosen the best response.1I'm glad you asked. When two figures are similar, and there is a scale factor between them, then the scale factor applies to the linear measurements. Look at these two cubes: dw:1439516359301:dw

Best ResponseYou've already chosen the best response.1Notice the cubes: linear scale factor: 1:3 = 1:3 area scale factor = 6:54 = 1:9 volume scale factor = 1:27 Notice that the area scale factor in the square of the linear scale factor, and the volume scale factor is the cube of the linear scale factor.

Best ResponseYou've already chosen the best response.1In your problem: AR = 10 & RE = 5, so AE = 15 Linear scale factor = 10/15 = 2/3 Area scale factor = (2/3)^2 = 4/9
