3x² + 7x² + 10x² = (3 + 7 + 10)x² = 20x² Assuming x = 1/2, we have: 20(1/2)² = 20(1/4) = 20/4 = 5 Answer: d) 5 P.S. I'm completely guessing at what you actually meant.

The given terms add up to 20x^2 and the answer depends on the value of x of which not enough information has been given

To simply add up 10 + 7 + 3 = 20 and obtain the answer 20X^2 is not worth calling genius. Any chance that your answers options [a) 3 b 7 c) 4 d) 5] are to do with another question ?

No, the "answer" isn't any of those. It's 20x^2.

3x^2 + 7x^2 + 10x^2 = 20x^2 You'll need to elaborate. What more do you want done with the expression?
