Factor the polynomial. b^2 + 4b + 4

(b + 2)^2

Step-by-step explanation:

b^2 + 4b + 4

It's perfect square: a^2 + 2ab + b^2 = (a + b)^2

So

b^2 + 4b + 4 = (b + 2)^2

The mixture has the intended volume and has the intended percent of butterfat.

Step-by-step explanation:

Point K is on line b, so it represents a scenario where the mixture has a volume of 500ml, start text, m, L, end text. Point K is on line a, so it represents a scenario where the mixture has 12, percent butterfat.So that would be the answer period
