Hint: Those terms are like terms. 

More obvious hint: 7a^2 + 3a^2 = 10a^2.

@Haksorin can you tell me what 7+4 = ?

anonymous · Answer

Twas D

kendricklamar2014 · Answer

Yes, D is the answer because 7+4 = 11, then you add the x^2 to make the answer: 11x^2

tyteen4a03 · Answer

@Haksorin @KendrickLamar2014 No. A like term consists of two parts: The coefficient (the number you see before the variable) and the variable itself, including any exponents (such as $x^2$ or $x^7$.

In this case, you are adding $4x^2 + 7x^2$. The variable is $x^2$ and must remain unchanged.

You got the answer wrong @tyteen4a03 You replaced 4 with 3. Im just saying that 7x^2+4x^2 = 11x^2

tyteen4a03 · Answer

@KendrickLamar2014 Answer D is $11x^4$, not $11x^2$.

Typing error Instead of putting 4 I put 2 :P
