Pedro wants to buy some shirts over the Internet. Each shirt costs $10.01 and has a shipping cost of $9.94 per order. If Pedro wants to spend no more than $70 for his shirts, which inequality shows the maximum number of shirts, p, that he can buy? 9.94 + 10.01p ≤ 70, so p ≤ 6 9.94 − 10.01p ≤ 70, so p ≤ 7 9.94p + 10.01p ≤ 70, so p ≤ 8 9.94p − 10.01p ≤ 70 ≤ 60, so p ≤ 9

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

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
