In the function f(x) = 4(x2 - 6x +_) +20, what number belongs in the blank to complete the square?
(2 points)

9

Step-by-step explanation:

you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.

So we would need to realize that the constant would be equal to (-6/2)^2  =(-3)^2 = 9

We have completed the square.

f(x) = 4*( x - 3)^2  + 20   is now in Vertex Form

21

step-by-step explanation:

11279

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
