Answer:
4x³ + 4x² + 5
Step-by-step explanation:
3x³ - 2x + 8 + 2x² + 5x + x³ + 2x² - 3x - 3.
4x³ - 2x + 8 + 2x² + 5x + 2x² - 3x - 3
4x³ + 4x² - 2x + 8 + 5x - 3x - 3
4x³ + 4x² + 8 - 3
4x³ + 4x² + 5
The answer is B
because
10*60=600 s
5*60=300s
2*60=120s
you have a total 1020 s
There's 24 hours in a day
so 24/100 = 0.24 < that is the percentage per hour
first eating - %10. 0.24x10= 2.4hrs eating
free time - 15% 0.24x15= 3.6hrs of free time
homework - 10% 0.24x10 = 2.4hrs of homework
school - 25% 0.24x25= 6hrs of school
and sleeping = 40% 0.24x40=9.6hrs of sleep
add them(hours) all up and you'll get 24!
