Tim loves reading fiction, and he can read 100 pages in 2 hours. how many pages he can read in 48 mins.

2 hours is equivalence of 120 minutes

If he reads 100 pages in 120 minutes,

the he reads (48 * 100) / 120 pages in 48 minutes = 4800/120 pages = 40 pages

He reads 40 pages in 48 minutes.

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
