Answer:
The simplified expression is: 12(7m - 6n)
Step-by-step explanation:
Greatest common factor between 84 and 72
We keep dividing 84 and 72, while they can be divided by the same factor. So
84 - 72| 2
42 - 36|2
21 - 18|3
7 - 6
So the greatest common factor is 2*2*3 = 12.
Rewrite 84m - 72n as a product of two factors
Evidencing 12
we are given
A jar contains 4 red marbles numbered 1 to 4 and 10 blue marbles numbered 1 to 10
so, total number of marbles =10+4=14
the number of marble that is red or odd number=2
so, the probability of the marble is red or odd number is
the probability the marble is blue or even numbered
= 1- P( the marble is red or odd number)
so, we get
the probability the marble is blue or even numbered is
