Answer:
7(9 + 14)
Step-by-step explanation:
The Greatest Common Factor of 35 and 63 is 7; both 35 and 63 are evenly divided by 7. Thus, 35 + 63 can be rewritten as 7(5) + 7(9), or 7(14)
So 35 + 63 = 7(9 + 14)
Answer:
Problems like this all have the same solution method.
If you have n letters, you start with n!. Then you divide by k! for each distinct set of k letters.
This is purely mechanical. E.g., if you have
AAAAABBBBCCC
DEFGHIJKLMNOP
there are 25 letters, and groups of 5 4 and 3
The answer is 25! / (5! 4! 3!). See, all you need to do is count the letters and then count how many times any letters are repeated. Then you can just write down the answer.
Once you know that, these problems are really, really easy.
