Step-by-step explanation:
we know that
The surface area of a cylinder (can of soup) is equal to
we have
----> the radius is half the diameter
substitute the values
Answer:
4×(x² - 4x + 2)
Step-by-step explanation:
4x2 - 16x + 8 = 4×x² - 4×4×x + 4×2 = 4×(x² - 4×x + 2)

you saved 2.40
please mark brainliest if correct :)
The value of x, when y is 2 is 3.
Therefore, g^-1 (2) = 3
Let y = 3x - 10, then x = (y + 10)/3
Therefore, h^-1 (x) = (x + 10)/3
(h o h^-1)(x) = h(h^-1(x)) = h((x + 10)/3) = 3((x + 10)/3) - 10 = x.
Therefore, (h•h^-1)(-1) = -1
