If your looking for individual ratios it would be
A: 3:8
B: 2:8 or 1:4
C: 3:8
Answer: -6x + 30
Step-by-step explanation:
First, distribute the numbers. By distributing 6 into the first equation, you end up with 6x + 24.
Then, distribute the -3 to the second equation, giving you -12x +6. After you have solved all of this, you should end up with -6x +30.
Answer:
125x³ − 150x²y + 60xy² − 8y³
Step-by-step explanation:
(5x − 2y)³
₃C₀ (5x)³ (-2y)⁰ + ₃C₁ (5x)² (-2y)¹ + ₃C₂ (5x)¹ (-2y)² + ₃C₃ (5x)⁰ (-2y)³
(1) (125x³) (1) + (3) (25x²) (-2y) + (3) (5x) (4y²) + (1) (1) (-8y³)
125x³ − 150x²y + 60xy² − 8y³
