The correct answer is A
Answer:
9/16
Step-by-step explanation:


Derivative rule:


Here, n=-1, so

Evaluating this at x=-4 gives 9/16
We have the following expression:

By combining similar terms, we get

now, 2 times 3 is 6 and to add exponents, both the exponents and variables should be alike:

Similarly,

Therefore, the answer is
Answer:
The answer is 18x - 8.
Step-by-step explanation: Trust me, an know a lot about math.
Answer:
f your number is x, then the difference between that number and 8 would be x-8. Twice that is 2(x-8)
Three times the sum of the number and 3 would be 3(x+3). So, you get the equation:
2(x-8)=3(x+3)
2x-16=3x+9
x=-25
