Answer:
the answer would be b
Step-by-step explanation:
the other 2 have negatives and the 3rd option is whole so b
Integers are negative or positive whole numbers
whole numbers do not include negatives
so ur answer is -3...it is considered an integer, but not a whole number
A and then A again, this is because you gotta leave the exponent by its self so you subtract 4 then the -4 gets to the other side and it leaves it with -6x = -24 then you just divide to get your answer.
<span>When order does not matter you use what is called n choose k formula
n!/(k!(n-k)!) where n is the number of things to choose from and k is the number of choices made, in this case:
20!/(4!(20-4)!)=4845</span>
