Use the discriminant to describe the roots of each equation, selecting all answer options that apply. x^2 - 4x + 4 = 0 (There are at least two) real and rational
root real and irrational root
double root
imaginary root

step-by-step explanation:

there are infinitely many solutions.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
