Answer:
1200
Explanation:
Order does not matter, if we said xyz order, it would still not make a difference if it was zyx or yzx hence we use the combination formula:
nCr = n! / r! * (n - r)!
where n= total number of items
r= number of items chosen at a time
Combinations are used when the order of events do not matter in calculating the outcome.
We calculate using the formula:
(30×20×12)÷3!=1200
There are therefore 1200 ways for the three distinct items to not be in same row or column

Hello there!
8 - 2x = -8x + 14
Let's start by subtracting 8 to both sides
8 - 2x - 8 = -8x + 14 - 8
-2x = -8x + 6
Let's add 8x to both sides
-2x + 8x = -8x + 6 +8x
6x = 6
Divide both sides by 6
6x/6 = 6/6
x = 1
The correct answer is option D
I hope this helps!
