7.)2a(a^2+4a)
A.)2a^2+6a^2
B.)2a^3
C.)2a+6a***
D.)2a^3+6a^2
C?
huh? really?
2a(a^2+4a)
= 2a(a^2) + 2a(4a)
= 2a^3 + 8a^2
check for typos...
wait watz the anwser?
EXCUSE ME???
I showed you the answer.
None of the choices matches. Check for typos in the problem or the answers offered.
As Steve told you, check for typos in your problem.
The answer to your problem is not one of your choices.
BUT U WROTE 3 ANSWER DOWN SO I'M ASKING WHICH IS THE ANSWER, So im wrong, its not"C" correct?
wait nevamind
I showed the steps in the solution, not three answers. See those "=" signs? That means that each line is equal to the one above it, not a new answer. It just shows the way to simplify the expression.
if you say so. Good luck with that.
Why do you post here if you're not going to pay attention to the answers?
Both of us told you that none of the choices matches the right answer.
To simplify the expression 2a(a^2 + 4a), you need to distribute the 2a to both terms inside the parentheses. This means multiplying 2a by a^2 and 2a by 4a separately.
First, multiply 2a by a^2. The product is 2a^3.
Second, multiply 2a by 4a. The product is 8a^2.
Now, we add the two terms together: 2a^3 + 8a^2.
So, the correct simplification is D.) 2a^3 + 8a^2.
Therefore, your answer choice C.) 2a+6a is not correct.
