Duval county landscaping uses two different sized trucks to deliver mulch. the first truck can
transport x cubic yards of mulch, and the second can transport y cubic yards of mulch. the first
truck makes 12 trips to a job site, while the second makes 14 trips. create an expression that
represents the difference in the total number of cubic yards that the first truck delivers compared to
the second

first one because it can't have a fraction in it

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

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
