Asked by Sheenybeany
                Point Q is the image of point P under a dilation with center O and scale factor 4. If PQ = 18, then what is OP?

    all distances also scale by a factor of 4.

    what 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.

    Like I said, the answer is wrong!  I put it into my online class and it said it was 6.  Thanks a whole bunch, Steve.

    Sheenybeany, stop being a jerk and saying it's wrong, its not, your peanut sized brain can't understand that the question says what is OP not what the scale factor is.
