Answer:
D
Step-by-step explanation:
263-239=24
I think the answer is 3 :))
... there is no math problem here
It looks like the differential equation is

Factorize the right side by grouping.


Now we can separate variables as

Integrate both sides.



You could go on to solve for
explicitly as a function of
, but that involves a special function called the "product logarithm" or "Lambert W" function, which is probably beyond your scope.
Whenever you see <em>x </em> next to a 3, and it says that it equals 9, you know that 3•3=9.
