Find the greatest common factor which is 9
9(9x^2-3x-2) and then factor the equation in the parenthesis
so the factored equation will be 9(3x+1)(3x-2)
In the table shown below:
Let N be the number of bottles filled,
Let T be the time in hours.
Given that the number of bottles filled is proportional to the amount of time the machine runs, we have

Let's evaluate the value of k for each day.
Thus, on monday,

Tuesday:

Wednesday:

Thursday:

It is observed that all exept wednesday have the same value of k.
Thus, the amount of time required for the number of bottles filled on wednesday is evaluated as

Hence, the incorrect day is Wednesday. The amount of time for that many bottles should be 6.85 hours.
Answer:
28
Step-by-step explanation:
probability of getting blue ball is 4/9
total cases = 72
i.e number of blue ball 32
number of red vall is 40
so extra 28 is added
I think you mean x^2 - 7x + 8
This is a basic factoring problem:
What two numbers multiply to make 8 and add to make -7?
There are no two numbers that work!
Therefore, it is prime
