The owners of a parking lot have determined that their weekly revenue and cost in dollars are given by R(x) = 80x and C(x) = 50x + 2400, where x is the number of long term parkers

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

the answer is 8.64
