Mathematics

Answer:

7

Step-by-step explanation:

To find the GCF, or greatest common factor, of a set of numbers, we should list out each of their factors.

21: 1, 3, 7, 21

28: 1, 2, 4, 7, 12, 28

After listing them out, we can tell that 7 is the greatest number that are in both of these lists.

21: 1, 3, 7, 21

28: 1, 2, 4, 7, 12, 28

So, 7 is the GCF of 21 and 28.

I need to make sure the first one is correct and the second question i need help with
stiks02 [169]

Answer:

First one: 9 units

Second one:  |2.5|, |-3|, |3.3|, |-4|

Step-by-step explanation:

9 units not negative 9 since you are counting the distance, not to or from, and the second one is the absolute value with each one, to simplify:

|-3|=3

|2.5|=2.5

|-4|=4

|3.3|=3.3

so the answer to the second one is |2.5|, |-3|, |3.3|, |-4|
