10C4 represent the Combinations of 10 objects taken 4 at a time.
The formula for nCr is:
![nCr= \frac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=nCr%3D%20%5Cfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D%20)
In the given case, n=10 and r=4. Using these values we get:
![10C4= \frac{10!}{4!(10-4)!} \\ \\ = \frac{10!}{4!*6!} \\ \\ =210](https://tex.z-dn.net/?f=10C4%3D%20%5Cfrac%7B10%21%7D%7B4%21%2810-4%29%21%7D%20%5C%5C%20%20%5C%5C%20%0A%3D%20%5Cfrac%7B10%21%7D%7B4%21%2A6%21%7D%20%5C%5C%20%20%5C%5C%20%0A%3D210%20%20)
This means we can make 210 combinations of 10 objects taken 4 at a time.
Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6
=(−n + 4n) + (−4 + 6)
=3n + 2
