f(x)=cg²t²x²
amintiți-vă că derivitive de af (x), în cazul în care a este o constantă este un lucru ori mai mare decât derivitve lui f (x)
f(x)=cg²t²(x²)

Answer:
36 years old (jim)
Step-by-step explanation:
looks like a good ol' word problem!
first, if you don't know what to do, always assign variables
Jim's age: x+9
June's age: x
Alex's age: x-8
we know the sum of their ages which is 82
so, x+9+x+x-8=82
simplify
3x+1=82
3x=81
x=27, but we're not done yet
Now we know x
jim: 36
june: 27
Alex: 21
so the oldest is jim at 36
