52² − 48² = (2704 + 2304)(2704 − 2304) = 2,003,200
52² − 48² = (52 + 48)(52 − 48) = 100 * 4 = 400
a² - b² = (a +b)*(a-b)
52² − 48² = 2704 − 2304 = 400

Answer:
- w + c > 5
- 49w + 100c < 400
Step-by-step explanation:
One inequality represents the number of bats. Their total number is more than 5:
w + c > 5
The other inequality represents the money spent. The total amount is less than $400.
49w + 100c < 400

<span>When the order doesn't matter, we would be using the Combination.
While, when the order does matter it is called permutation.</span>
In this case, permutation would be use since there is a
ranking for the albums.
We need to choose and arrange 5 albums out of 20. Hence, the
number of possible ways will be:
<span>5/20 P = 20! Divided by (20 – 5)! = 20 x 19 x 18 x 17 x 16 =
