It is not A.  You only add like terms.  Like means the same power.

anonymous · Answer

its c!

e.mccormick · Answer

Or to be clearer (mathemeatically proper) you only combined like terms. So how manay total things to the 9th do you have?  Then how many total to the 6th?  Then first power.  And last the ones without an x.

5x9 + 3x6 + 19x + 3

e.mccormick · Answer

You can rewrite that as one long equation... \[[3x^6+7x+3]+[5x^9+12x]\ That ehlp you see why A and C are wrong?

e.mccormick · Answer

Hmmm... It dropped me out of equation mode.  LOL.  $$[3x^6+7x+3]+[5x^9+12x]$$

e.mccormick · Answer

Ah, yes, you typed out B in long form, which is correct!

e.mccormick · Answer

I missed it at first with the powers not using ^ or the equation editor.  Sorry bout that.
