3x(9x² + 11x - 5) + 2(2x³ + 11x - 5x²) - 5x² + 8
Simplify.
27x³ + 33x² - 15x + 4x³ + 22x - 10x² - 5x² + 8
Add like terms.
(27x³ + 4x³) + (33x² - 10x²) + (-15x + 22x) + 8
Simplify.
31x³ + 23x² - 7x + 8

Answer: 82.3 g
Step-by-step explanation:Moles Cu = 300 g x 1 mol Cu/63.55 g = 4.72 moles Cu
Moles Zn = 4/15(4.72) = 1.26 moles
mass Zn = 1.26 moles x 65.38 g/mol =
We are trying to find it's speed which is measured in miles per hour or miles/hour
So: 375 miles/7 hours
This simplifies to 53.5714286 miles per hour.
Yes, 6/8 reduces to 3/4 by dividing the numerator and denominator by 2.
