Consider expression 
First, you can factor it:
Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus, 
is always even.
Answer:
-4,-4
Step-by-step explanation:
Answer:
There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.

Answer:
Equation: 15 - f = n
Answer: n = 9
Step-by-step explanation:
The question is asking to write the equation. The equation would be
"15 - f = n" where f shirts folded
n = shirts remaining to fold
Then the question has gave us the value of f and has told us to solve it. Below is the solution.
15 - 6 = n
=> n = 9
Therefore, there is 9 shirts remaining after 6 of them are folded.
What did we solve?
We wrote our equation and solved what was required in the question.
I hoped this helped.
If possible... May I have brainliest :)
