Answer:
I think its the lifo method im not sure but i had a question like this in class
This is a division of polynomials
8x^3 - 28x + 61 | 2x + 5
-----------------------
- 8x^3 - 20x^2 4x^2 - 10x + 11x
---------------------------------
0 - 20x^2 - 28x + 61
+20x^2 +50x
------------------------
0 +22x +61
-22x -55
----------------
6
Then, the division is not exact and the result is 4x^2 - 10x + 11x with remainder 6, or:
4x^2 - 10x + 11x + [ 6/ ( 2x + 5)
Answer:
x > 6 and x ≤ 10
Step-by-step explanation:
You have to sleep for more than 6 hours, which means it is greater than and can not be equal to because it has to be more than 6 hours.
For the second problem, at most includes the 10th person so x is less than or equal to 10.
Hope this makes sense!!
