Simplify the rational expression 6x(x+3)(x-2)/3(x-2)(x+9) a) 2x/x-3 b)2x/(x-9) c) 2x(x+3)/(x+9)

An observer(o) spots a plane(p) taking off from a local airport and flying at a 29 degree angle horizontal to her line of sight and located directly above a tower(t). the observer also notices a bird circling directly above her. if the distance from the plane(p) to the tower(t) is 6,000ft., how far is the bird(b) from the plane(p).
