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
That is actually true. Everything thats multiplied by 0 eaquals 0.
Answer:
B. Commutative Property of Addition
Explanation:
To find out the property that would not be used in solving this equation, we solve for g.

We have applied the following:
A. Addition Property of Equality/D. Subtraction Property of Equality
C. Division Property of Equality
Therefore, the property that would not be used is:
B. Commutative Property of Addition
