It's actually 14a + 18
They don't have the same literal (a), 18 doesn't even have one, so you can't add them.
If the ecuation was 14a + 18a, then you can add them, cause they would have the same literal (the same letters)
Answer:
It is NOT. See below.
Step-by-step explanation:
That is only the second or third time I've seen that on Brainly. You cannot add 14a and 18. The 14 is coupled with a variable (a). The 18 is not.
Rule: You cannot join two number whose variables are not exactly the same.
The answer to 8a^2b + 8ab^2 is 8a^2b + 8ab^2 unless you know about the distributive property but even then, you cannot destroy that plus sign.
Answer: The answer to 14a + 18 is 14a + 18. Don't destroy the + sign.
Edit
You can factor them. That would use the distributive property. 2*(7a+9) would be the way to factor it. But that plus sign never goes away under these circumstances.
