Which algebraic expression is a polynomial with a degree of 3? 4x3  –  2y3 + 5y2  – 5y 3y3  –  –xy

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

`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. ''.

Def rotates 90 clockwise about point a to create d’ e’ f’. therefore, which equation must be true ?
