A waterfall is n times the height of its picture on a postcard. Which equation represents the height, y, of the waterfall if the
picture is 7 cm tall?
A y = 7n
By = 7+n
y=n-7
y = 7n

it is not that hard all u have to do is plot the graph

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
