Refer to the graphic novel frame below. How many Black T-shirts would Hannah and Dario need to sell to make up the loss in profit? (Graphic Novel) Dario: "It looks like we spend $15 on every black T-shirt that is printed on both back and front. We should give one to the mascot for free." Hannah: "We sell the black T-shirts for $18 each." Also, I'm in 7th grade not 10th..

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)

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
