Scientists have discovered a new type of virus. The number of cases reported, c, can double every hour, h. If there are 300 known cases of the virus, what could be an equation for this situation?
c = 2h + 300
C = 300h + 2
c = 30052
C= 300(2)"

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.
