Answer:

The correct option is C.

Step-by-step explanation:

The given expression is

21x-18x+28xy

The factors of each term are

21x=3\times 7\times x

18x=3\times 6\times x

28xy=2\times 2\times 7\times x\times y

The common factor is x.

G.C.F.=x

Therefore correct option is C.

The answer i got was c because the letter x goes into each of them because they each have a x in them. It would be B but 3 doesnt go into 28.

[True]

Natural numbers are the positive integers (whole numbers) such as 1, 2, 3, and etc. So it is true that zero is less than every natural number.

[Hundreds]

The 8 in 30,846 is in the hundreds place because the 8 stands for 800.
