The variables X and why vary directly use the values to find the constant of proportionality and write an equation that relates X and Y write the equation in the form Y=KX 1. y = 4; x= 6
2. y = 2; x = 10

Step-by-step explanation:

dont mind that it means the answer i dont speak english but thats the answer in peru

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
