You should try to divide 192 by the 4 sides on the rectangle.
The correct answer is x=3
2 X 5 X 23
this is the prime factorization of 230 :3
Answer:
x1=-(square)7+5 x2=(square)7+5
We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.
This gives
f'(x) = 7
Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.
