Prisilla performs a series of transformations on a figure in the plane. First she dilates it by a factor of 3 and translates it 5 units to the right. Next she reflects it over the x axis, then over the y axis. Finally she reflects it over the line y=x, translate it 5 units to ...

The perimeter of the polygon below is 9x-1. Find the expression for the missing side length. There are 5 expressions: 3x-4, x-5, x+1, 2x+3, and ?. I got ?=2x-6. I added all the equation and minus it from 9x-1.

They are vertical angles.

There are four angles, a,b,c,d. The measure of angle a is (3x+10) degrees. The measure of angle d is (x+10).What is the value of x? I made an equation 3x+10=x+10. I think the value is 0.
