What polynomial has roots of −5, −4, and 1

D

Step-by-step explanation:

The question continues with these options:

a. x3 − 8x2 − 11x + 20

b. x3 − x2 + 22x + 40

c. x3 + x2 − 22x − 40

d. x3 + 8x2 + 11x − 20

A cubic in equation (x+5)(x+4)(x-1) or on a graph that crosses at -5, -4, and 1. Multiply the factors out to find the equation.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

the answer is b.)
