Answer:
Step-by-step explanation:
perhaps you mean
x^3+y^3+z^3 = 3xyz
because
x+y+z = 0
x^3 + y^3 + z^3 - 3xyz = (x + y + z )(x^2 + y^2 + z^2 -xy - yz - xz)
(this equation is an identity)
x^3 + y^3 + z^3 - 3xyz = (<em>x + y + z</em> )(x^2 + y^2 + z^2 -xy - yz - xz)
x^3 + y^3 + z^3 - 3xyz = (<em>0</em>)(x^2 + y^2 + z^2 -xy - yz - xz)
x^3 + y^3 + z^3 - 3xyz = 0
x^3 + y^3 + z^3 = 3xyz
Answer:
x = - 4
Step-by-step explanation:
Hi there !
if f(x) = 2x + 7 and f(x) = -1 =>
2x + 7 = - 1
2x = - 1 - 7
2x = - 8
x = - 8 ÷ 2
x = - 4
Good luck !
Answer: A - 3/18
Step-by-step explanation: 1/6 can equal to 3/18 because 6 x 3 = 18 and 1 x 3 = 3. Hope that helps!
