Ruden bought 6 new books for his collection, increasing his collection by 12%. How many books did he have before his purchase?

forsale [732]

Answer:

he had 44 books before he bought those 6

Step-by-step explanation:

If you multiply 6 times 2 it is 12, which means if you take away 12 from 100 that is 88. if you divided 88 by 2 (the same thing you did to the 6 to make it 12%) that would be 44.

PtichkaEL [24]

The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4
