x³ + y³ + z³ - 3xyz is a multiple of x+y+z.
It should be noted that a multiple simply means a number that van be divided by another a certain number if times without a remainder.
Put x + y + z = 0
= x³ + y³ + z³ - 3xyx
= 0(x² + y² + z² - xt - yz - zx)
= x³ + y³ + z³ - 3xyz = 0.
x³ + y³ + z³ = 3xyz

Answer:
B
Step-by-step explanation:
To be a function every input must have exactly one output. There are two input values with 2, therefore this makes it not a function.
R = 7cm
D = 14cm
CF = C = dπ or C = 2rπ
CV = C = 14π or 2( 7π )
A.40 J
K. E. Is 1/2 multiply by mass x velocity square
M is 5kg, v is 4m/s
1/2 x5x4x4 equals 40joules.
