Base, b, and height, h, of rectangles with an area of 100 centimeters squared. Check all that apply.

Choice 1 :bh = 100
Choice 2: 100b = h
Choice 3: b = 100/h
Choice 4: h = 100/b

Which apply?

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

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
