Well it is definately not c haha. I would say 3 because it is a pretty even chance of getting three.
Answer:
12
Step-by-step explanation:
6 * x = 72
x = 72 / 6
x = 12
Factors of 12 : 1, 2, 3, 4, 6, 12
Factors of 20: 1, 2, 4, 5, 10, 20
In both lists of factors, 4 is in common. Therefore, the value of K is 4 because it can divide into both 12 and 20 without a remainder. 2 is also another possible value of K.
