A ladder is 21.7 ft long and reaches 15.9ft upbrhe wall. what angle does the ladder form with the ground?

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

you,

mrb

the answer is 3/2 and for decimal: 1.5
