Please help me???.

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

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

1/2+1/6-3/4 simplify the given expression leaving the answer in improper fraction form.
