Which equation is the inverse of 2(x – 2)2 = 8(7 + y)? –2(x – 2)2 = –8(7 + y) y = one-fourth x squared minus x minus 6 y = negative 2 plus-or-minus StartRoot 28 + 4 x EndRoot y = 2 plus-or-minus StartRoot 28 + 4 x EndRoot

can you me with homework?

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

570, the answer is 570, hope it
