Answer:
5(4k + 3)
Step-by-step explanation:
What is the common factor of 20 and 15?
It is 5.
So you can take the 5 out of both of them and divide both of them like
5 times 4 and 5 times 3
You now get rid of the 5
5(4+3)
BUT WAIT
there was a k in 20k.
So you
put the k next to the 4.
So you get
5(4k + 3)
done
