Do you know how to integrate or are you just having problems with this specific problem?

anonymous · Answer

If I took the integration of 5x+7 it would be 5x^2 /2  
But how does the 7x get in there?

sanchez9457 · Answer

when you integrate any number, a consant, you get that number times x.

anonymous · Answer

I guess dx of 7x is 7 so anti is 7x

sanchez9457 · Answer

or that number times whatever the variable you are integrating with repspect too

anonymous · Answer

I just didnt see the process
thanks so much for your help if you didnt say anything I would have just been sitting here stewing even though I knew the answer

sanchez9457 · Answer

yes exactly! the derivative of 7x is 7! and the anti of 7 is 7x! Exactly!
