For this case we have that by definition, the Greatest Common Factor (GCF) is the largest factor that 2 numbers have in common.
So, we have the following expressions:

We look for the positive integers that divide to 35 and 42 without leaving residue:
42: 1,2,3,6,7,14,21
35: 1,5,7
Thus, the GCF of 42 and 35 is 7
Then, the GCF of the three expressions is:

Answer:

Answer:
Step-by-step explanation:
8.18
Answer:
33x + 3
Step-by-step explanation:
To expand an equation like the one you have shown, multiply the 3 with everything inside the parenthesis.
3*11x=33x
3*1=3
Answer:
The numbers larger than -2 and smaller than 3 are -1,0,1,2.
