Answer:

18

Step-by-step explanation:

(Note: I'm assuming that "starts out with" refers to the count before buying the four boxes)

Let x be the number of boxes Emily starts out with.

(x + 4) / 2 = 11
\frac{x}{2} + \frac{4}{2} = 11
\frac{x}{2} + 2 = 11

We multiply both sides by 2 to eliminate the fraction.

x + 4 = 22

x = 22 - 4

x = 18

I'm not sure where to start and how to differentiate this.
Mazyrski [523]
The picture is not clear. let me assume y = (x^4)ln(x^3)

product rule :
d f(x)g(x) = f(x) dg(x) + g(x) df(x)

dy/dx = (x^4)d[ln(x^3)/dx] + d[(x^4)/dx] ln(x^3)
= (x^4)d[ln(x^3)/dx] + 4(x^3) ln(x^3)

look at d[ln(x^3)/dx]
d[ln(x^3)/dx]
= d[ln(x^3)/dx][d(x^3)/d(x^3)]
= d[ln(x^3)/d(x^3)][d(x^3)/dx]
= [1/(x^3)][3x^2] = 3/x
... chain rule (in detail)

end up with
dy/dx = (x^4)[3/x] + 4(x^3) ln(x^3)
= x^3[3 + 4ln(x^3)]
