The answer is:
−6x2 + 2x − 4
Solution: 12x^3 - 4x^2 + 8x ÷ -2x = -6x +2x - 4
The cylinder is symmetric across the plane

, so we need only consider half of the cut-out region.
This region can be parameterized by

with

and

. Then the area of this half is given by the surface integral



Doubling this gives a total area of 72.
Answer:
217 is the perfect swuare i think
Answer:
- 3 1/4
Step-by-step explanation:
-2 1/2 - x = -5 3/4
(Add 2 1/2 to both sides)
- x = 3 1/4
(Make x positive)
x = - 3 1/4
8/3 (plz give me brainliest)
