In this item, it is not given that there has to be specific arrangement or order as to how the questions are going to be answered. Hence, the concept that can be used in order to answer this item is the concept of combination which states that,
nCr = n! / (r!)(n - r)!
This is read as "combination of n taken r". In this item, n = 10 and r = 4. Substituting the known vaues to the equation,
10C4 = (10!) / (4!)(10 - 4)!
10C4 = 210
Therefore, the number of which is which the questions can be answered is 210.
8 x 7 x 10 x 6 = 3360 ft . I believe this should be the answer.

Step-by-step explanation:
Answer:
(8m+24n) is our final answer.
Step-by-step explanation:
Given:
(m+3n)8 ...
We have to simplify this.
Applying distributive property of multiplication:
Distributive property:
When a number is multiplied by a sum of two numbers then we will multiply 'the number' first with the number inside the parentheses then add it and again multiply 'the number' with the next number.
![a(b+c)=ab+ac](https://tex.z-dn.net/?f=a%28b%2Bc%29%3Dab%2Bac)
So,
⇒![(m+3n)8](https://tex.z-dn.net/?f=%28m%2B3n%298)
⇒![m\times 8 + 3n\times 8](https://tex.z-dn.net/?f=m%5Ctimes%208%20%2B%203n%5Ctimes%208)
⇒![8m+24n](https://tex.z-dn.net/?f=8m%2B24n)
Our final answer is (8m+24n).
