Answer:
6
Step-by-step explanation:
The value of X is 7 because of the mean value theorem and the second derivative test.
If you multiply the fractions, you get 10/27 which can’t be simplified.
Ok so what we have to do is 4+7+9=c
4+7=11
11+9=20
c=20
your answer is 20
The final answer would be 39/19 it doesn't simplify any more and if it did the 19 would be reduced as well as the 39
