Show that 2/4-x = 10/4-x is equivalent to 12x=32 for all values of x not equal to 4 or -4

i think it might be a but you might want a second opinion

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

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,
