What is the speed of the car and motorcycle?

Step-by-step explanation:

 CAR /50 km/hTypical car speed on residential roads or busy city roads

80–90 km/hVehicle on main road, travelling reasonably fast

100–120 km/hFast car on motorway, typical speed of a cheetah running, freight trains

200–300 km/hHigh speed train

hello from mrbilldoesmath!

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

discussion:

in general, the factorization of a^3 + b^3 is

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

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

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

mrb

(a + b) (a^2 - a b + b^2)
