A traffic study determined that a larger city population indicates a longer commute time for drivers. What can we say from this

information?

There is no correlation between commute time and city population.

There is a correlation between commute time and city population. However, there is no causation. This is because there is an increase in the

commute time with an increase in the city population.

There is a correlation between commute time and city population. There may or may not be causation. Further studies would have to be done to

determine this.

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)
