Find the greatest common factor. 2r, 4r

Mathematics
1 answer:
ipn [44]3 years ago
5 0

Answer:

GCF: 2r

Step-by-step explanation:

The Greatest Common Factor(GCF) is the biggest factor you can divide both numbers by. For these numbers we cannot divide by a bigger number than 2r, and that happens to be the greatest common factor because 4r can be divided by 2r.

Hopes this helps!

Vikki [24]

We are given the expression,

54x+81

Here we have to find Greatest Common Factor of 54 and 81

Factors of 54 are 1, 2, 3, 6, 9, 18 and 27.

Factors of 81 are 1, 3, 9, 27 and 81.

Greatest common factor of 54 and 81 is 27.

So we take out 27 common, rewriting the expression

27(2x+3)

Answer: 54x+81 in factored form equals 27(2x+3).

How do you do -19+C/3=8 can someone teach how to solve this problem?
ki77a [65]
You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
