Simplifying radicals maze, please help me with this!!!

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7

Need solving this second acceleration problem.

What is the radical expression that is equivalent to the expression 27 1 over 5?
