The Carousel in the City of Weston Fair has 2 rings of horses. Andrea is riding on the inner ring, which has a radius of 8 feet. Fabiana is riding on the outer ring, which is 5 feet farther out from the center
than the inner ring is.
1. In one rotation of the carousel, how much farther does Fabiana travel than Andrea?
2. One rotation of the carousel takes 10 seconds. How much faster does Fabiana travel than Andrea?

answer is 33

step-by-step explanation:

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)

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