The solution for the given division problem.
Solution:
We have,

Here, 4x^4-4x^2-x-3 is the dividend and (2x^2-3) is divisor.
Using the long division method we get


(After subtraction)

(After subtraction)

.
Answer:

Step-by-step explanation:
Given



Orchestral =
of music practice time
Required
Determine time spent on orchestral pieces
From the given parameters, we have:
Orchestral =
of music practice time
Substitute
for music practice time.
So, we have:



The third one is r=-10 (don't forget the negative!)
The fourth one is p=-3 (again, watch for the negative)
((I can't get the fifth one, sorry. You might want to repost another question with just that one))
The sixth one is w=35.
Hope this helped a little bit! Sorry I couldn't help with all of them .-. Good luck though!
Answer : 4.5 × 10⁴ square inches can be washed per hour.
Step-by-step explanation :
As we are given that an area can be washed at a rate of 4,900 cm²/min. Now we have to determine the square inches can be washed per hour.
Given conversions are:
1 cm = 0.39 in and 1 hr = 60 min
As, 1 cm² = (0.39)² in² and 1 min = 1/60 hr
So, 

Now we have to determine the square inches can be washed per hour.
As, 
So, 
Therefore, 4.5 × 10⁴ square inches can be washed per hour.
