Please help ! 100 points ! What is the correct classroom for each given angle

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

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
