Answer: X=5
Step-by-step explanation:
-8=(X+11)/-2
* start by multiplying both sides by -2
16=X+11
*subtract 11 from both sides
5=X
X^2(x+2)-4(x+2)
(x^2-4) (x+2) = 0
do you have to keep going/?
or thats all they want?
This just wants the derivative which you can solve for.
You can do this using a negative expononet or using ...the rational rule forget its name*.... you shoudl get 9000/(t+12)^2
*Quotient rule
