Answer:
D. du/dx = 2x
Step-by-step explanation:
Given to find dy/dx where;

Then when you let;
u=x²+2 and

Then
In u=x²+2 du/dx = 2x------------------------step 1
In e^4x, dv/dx = e^4x * d/dx (4x)
=e^4x *4 = 4e^4x------------------------------------step 2
This is pretty simple, you just add up the percentages and that would give you 65%, now you figure out 65% of 320 and google will tell you it is 208. now you have two possible answers, i am not sure if your question is asking for a percentage or an exact amount if it is parentage the it would be 35%, if it is exact then it would be 320-208 which is 112. so your answer probably is 112 students chose other.
