I don't get why your pics are so small, please make them bigger if possible. Or just actually write it yourself like so... I'm going to write this so people can actually read it: $\Large \int\limits_{0}^{2} x \sqrt{ 4x^2 +9} dx$

5. onegirl

okay

6. onegirl

yea thats correct

7. agent0smith

As long as you used u substitution with u=4x^2+9, du= 8x dx, it should be correct. 49/4 isn't correct, but it's close.

8. onegirl

okay i tried again and i got 49/6

okay so my question has multiple choices and in them none of that has 49/6

11. onegirl

there is 32/3, 15/4, 80/9 and 49/4

12. robtobey

Mathematica returned 49/6

13. onegirl
