What is the gcf In this problem
scoray [572]
Find the GCF of 88 and 24 first 

88=2*2*2*11 
24=2*2*2*3 

The GCF for 88 and 24 is 8 
The GCF for r^18 and r^13 is r^13 (because they both contain r^13 in them) 

=8r^13(11, 3)

I have no idea how to do this, pls help. Question in the picture. Please show your work. Thanks!

Answer:

C

Step-by-step explanation:

This is a stem and leaf plot. If you don't know what a stem and leaf plot is, try searching it before coming back and viewing the solution. I also see an "example" button. It might help to hit that too.

First, we sort the list of numbers. Here is what we get:

64, 66, 67, 68, 69, 74, 75, 76, 78, 79

Here, the stems are the tens digits and the leaves are the ones digits.

Therefore, for the stem 6, the leaves are:

4, 6, 7, 8, 9

For the stem 7, the leaves are:

4, 5, 6, 8, 9

The answer, I believe, is C
