Distribute 6
8x-18+12x
20x-18
it is an expression so no answer
Answer:
The first one is by using your mind. If you know that factorial of any non negative integer denoted by n!
defined as
n!=n(n−1)(n−2)⋯3⋅2⋅1
then 5!=5∗4∗3∗2∗1. You can calculate it in your mind which will give you 5!=120.
That's it.
The next method is using your calculator. In my calculator Casio fx-991es, I pressed 5 and then shift+x−1
button and I got 120. Similarly, you can use Google to calculate it like I did and got this.

Answer:
LCM = 540
Step-by-step explanation:
Prime factors of each number:
18 = 2*3²
54 = 2*3³
60 = 2²*3*5
Since they don't necessarily have prime factors in common, we multiply the largest prime factors together:
2²*3³*5 = 4*27*5 = 540
