Answer:
Step-by-step explanation:
integral(x/(1+x^2)^2)dx
=(1/2)integral(2x/(1+x^2)^2)dx
=(1/2)[-1/(1+x^2)] +c

Hope this helps!:)
The answer is false. I hope this helps love! :)
9/10 - 5/10
because the denominators are the same you keep it and just subtract the numerators
=4/10
This can be reduced to 2/5
I think it’s B, or 0.10x+0.15(50-x)=0.12(50)
Because 10% would give you 30ml, and 15% would equal 20ml to get 50ml, according to the equation.
