(f-g)(x) is equivalent to f(x) - g(x)
So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3
Hope this helps.
The volume of a cylinder is represented by:

We know that r is equal to

, and d in this case is 9 in. Therefore, r = 4.5 in.
Then, using 3.14 for

, and 15 in. for height, we can solve for the volume of the cylinder:



By using this equation, we were able to determine that the volume of this cylinder is
.
The answer is A. If you plug 12 into x and 6 into y, it would make sense.
12=2(6)
2×6=12
12=12
Hope this helped even though you have the answer :)
The first one
1 because if your see it on the scale it shows -2 and 2 then add that up there you go
The 2 one jaydjdisgnsjsyhdndisbss.
