It would be six because they are like terms.
So what you do,is you add them together to get 13/10 but then you can also simplify it but you can keep the answer to 13/10

Multiply .65 by 540 which gives you 351.
In order to name the coordinates, you read the X axis first and then the Y axis. So A would be (-4, 4). B would be (-4, 6). C would be (2, 4).
They are not congruent because each angle is a different measure.
Hope this helped! :)
