use geometric formula to find 4-x and 2x-8 when integral is from 0 to 6

To find the values of 4-x and 2x-8 given the integral from 0 to 6, we need further information as to what function is being integrated. The geometric formula is not directly applicable in this case.

If you provide the function being integrated, I can help you find the values of 4-x and 2x-8 by evaluating the integral.
