**Steve**, Thursday, July 31, 2014 at 7:03pmall distances also scale by a factor of 4.

**Sheenybeany**, Thursday, July 31, 2014 at 7:18pmSorry, but that's not right :(

I really need to do this. Any help?

**Steve**, Friday, August 1, 2014 at 6:04amwhat do you mean by "that's not right?" What calculation did you do?

Without loss of generality, we can take the distances to be measured along the x-axis.

We have two points, P and Q on the x-axis, where

OQ = 4(OP) because of the dilation.

Since PQ=18, that means that 3/4 of the distance OQ = 18.

So, OQ = 24 and OP = 6.

All because the distances grew by a factor of 4, as I said.
