The solution is subtract4.7x on both sides. Then you get -2.2x=7.7. Divide 7.7 by -2.2 and you get x= -3.5
Answer: 21599373.37618
Step-by-step explanation:
X shortest piece
X+6 middle piece
X+8 longest piece
Add them
3x+14=56

X=42/3=14
Answer:
16x / 15
Step-by-step explanation:
2/5x + 2x/3
6x - 10x /15
16x / 15
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
