Answer 2

the scale factor is the ratio of the 2 sides you know to be equivalent

they are the 2 numbers you are given

Answer 3

Scale factor is the number you multiply the sides by in the first figure to get the second figure sides. So let's look at MNL. We have one side given which is 18. Now let's look at the other figure. THe side is 10.8

What do you multiply by 18 to get 10.8?

Answer 4

194.4

Answer 5

Not quite, haha

Answer 6

You don't multiply 18*10.8, you divide 18/10.8

Answer 7

A?

Answer 8

Right! Because you multiply 18*0.6 to get 10.8
