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:

$$\Large \int\limits_{0}^{2} x  \sqrt{ 4x^2 +9} dx$$

anonymous · Answer

okay

anonymous · Answer

yea thats correct

agent0smith · Answer

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.
