Porfa ayuda : la suma de las areas de 2 irculos es de 65 pi cm^2. el radio del circulo mayor R mide 1cm menos que el doble del radio del circulo menor, encuentre la medida del radio de cada circulo ecuacion de segundo grado

ask the math teacher she or he would know lol.

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

●yes, this statement is absolutely apt.

hope this you
