Sherry and Kari both started their hike with a small bottle filled with water. Tia started her hike with a larger bottle that was ½ full. At the end of the hike, Sherry and Tia’s bottles were each half filled with water. Karl’s bottle was 1/3 filled with water. Who has the most water left? Construct a math argument to support your answer.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

step-by-step explanation:

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
