Times means multiply
Is means equal to

So all we have to do is set it up in an equation:



So now let's solve for

Get all s to one side:



Now get all of the numbers to one side:



Now let's solve for :



So x=8

127 millimeters is the answer

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
