Answer:
<em>(n - 5)(n + 5) </em>
Step-by-step explanation:
a² - b² = (a - b)(a + b)
n² - 25 = n² - 5² = <em>(n - 5)(n + 5)</em>
N is -4 because -4x2=-8 and -8+3=-5

Add all the chips to find the total amount.
7 + 9 + 3 + 6 = 25 chips
Since there are 6 blue chips (6/25), that's the probability of just getting once.
When you pick a blue chip and it doesn't get replaced, then that means there is one fewer blue chip and one fewer from the total amount.
5/24
Multiply both probabilities.
6/25 * 5/24 = 30/600
Simplify.
30/600 → 1/20
Therefore, the answer is B
Best of Luck!
An = a1 + (n-1)d
an = 27 + (n-1)(-6)
