6x+5y=-15
5y=-15-6x
y=(-15-6x)/5
You would use 539 and square it on you cal. just once. Then once you do that the answer is not going to be a whole number it is going to have a decimal, so the answer would be 23.22.

Answer:
- (d) (x² + y² + z²)³ = 27x²y²z²
Step-by-step explanation:
<u>Use the identity:</u>
- a³ + b³ + c³ = 3abc if a + b + c = 0
<u>Substitute as follows:</u>
<u>The sum of the cubes is:</u>
- x² + y² + z² = 3(xyz)

<u>Cube both sides:</u>
- (x² + y² + z²)³ = 27x²y²z²
Correct choice is (d)
