Morgan wants to swim directly across a river, from the east to the west side. she swims at a rate of 1 m/s. the
current in the river is flowing due north at a rate of 3 m/s. which direction should she swim so that she travels due
west across the river?

the probability that a bird is green (.30) is true

step-by-step explanation:

yes

step-by-step explanation:

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 a.
