Well you need to find a common denominator which 30 is the closest one. 5/6 becomes 25/30, 9/10 becomes 27/30. 27/30+ 25/30 = 52/30. To simplify that you divide by 2 to get 26/15. It is no longer divisible to a whole number after that point.
2p = 4
p = 2
-2p = 4
p = -2
answer p = -2 and p =2
If you graph 4 separate triangles with the four different points, (2,3) and (1,5) form a right triangle.
