You would have to have 20 minutes of studying per hour of class time. This means that 60 times 2=120. 120-90=30. 30 minutes is half an hour. So you would do 20 divided by 2 since u are adding another half hour to studying. You would add 60 and 10 to get 70 as your answer I think. I hope this helps and is correct :)
If we are looking to simplify two trinomials, it is easiest to put them on top of each other and subtract.
7x² - 2x + 5 7x² - 2x + 5
- (3x² + 4x + 10) -3x² - 4x - 10
4x² - 6x - 5
Answer:

I=prt
so we just multiply everthing together
800*0.03*6=144
