Have you ever tried to hold your breath? Humans can only hold their breath an average of one minute. However, other animals can hold their breath for much longer. A whale can hold its breath six times as long as a beaver, and a hippopotamus can hold its breath ten minutes less than a beaver. If you added the time a whale, beaver, and hippopotamus can hold their breath, you would get 110 minutes! Use the 5-D Process to define a variable and write an equation for this situation. Which animal should represent the variable "x" in your equation? PLS HELP PLS ASAP THIS IS A TEST

idk bring the function back   im not smart

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

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)

you,

mrb

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