Answer:
5(4x+3)
Explanation:
We first have to find the GCF(Greatest Common Factor) of 20 and 15.
We get 5 as our GCF.
Take the 5 out of the parentheses.
5()
Then we have to divide 20x and 15 by 5
4x and 3
After, we put this value into the parentheses, making our answer correct.
5(4x+3).
To check, we have to distribute 5 to 4x and 5 to 3.
20x+15.
Our answer is correct!
