What is the angle type and what is the value of x? also explain how you got your answer.

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

A.s.a.! this is a similarity in right triangles. next (solve for x)a.) 12b.) 5c.) 12.5d.) [tex] 6\sqrt{3} [/tex]

Which equation represents a direct linear variationa. y=x2b. y=2/5xc. y=1/xd. y=x+3
