Answer:
6!=720
3! • 2!=12
Step-by-step explanation:
We must recall that the factorial of a number n (positive or zero) is the product of all the integers from n down to 1
n!= n(n-1)(n-2)...1
Let's evaluate the given expressions
6!=6\cdot 5\cdot 4\cdot 3\cdot 2\cdot 1=720
Similarly
3!\cdot 2!=(3\cdot 2\cdot 1)\cdot (2\cdot 1)=6\cdot 2=12
Finally
\displaystyle \frac{6!}{3!}=\frac{6\cdot 5\cdot 4\cdot 3\cdot 2\cdot 1}{3\cdot 2\cdot 1}
\displaystyle \frac{6!}{3!}= \frac{720}{6}=120
Answer:

Answer:
They are 24ft apart.
Step-by-step explanation:
Larry is 6 feet above sea level, so his height is 6.
Damian is 18 feet below sea level, so his height is -18.
How far apart are larry and damian
To find this, we subtract their heights.
6 - (-18) = 6 + 18 = 24
They are 24ft apart.
