Which second degree polynomial function has a leading coefficient of 2 and roots –3 and 5? f(x) = 2x2 + 4x – 30 f(x) = 2x2 + 2x – 15 f(x) = 2x2 – 4x – 30 f(x) = 2x2 – 2x – 15

If you have a set of parallel lines a and b cut by transversal x, if angle 1 = 167 degrees, what is angle 4 and why. also what is the measure of angle 5 and why? you need to use the names of the angle relationship and explain.
