Can a triangle be formed with the sides lengths of 9 cm, 2 cm and 11 cm

You are studying different function tools and begin working with this function y=-160-9(x) use the equation to answer the question y=-160-9(x) what is the y value when x equals -13? y=-160-9(x)

(a) solve h+2/6 = h-3/4(b) solve the following simultaneous equations. 2x = y + 66x - 2y = 13x = ? y = ?

1. are the triangles similar and if so why? what is the value of x? show your work.
