Step-by-step explanation:
Given the following functions:
r(x) = x - 6
s(x) = 2x²
r(s(x)) = r(2x²)
Replacing x with 2x² in r(x) will give;
r(2x²) = 2x² - 6
r(s(x)) = 2x² - 6
(r-s)(x) = r(x) - s(x)
(r-s)(x) = x - 6 - 2x²
Rearrange
(r-s)(x) = - 2x²+x-6
(r+s)(x) = r(x) + s(x)
(r-s)(x) = x - 6 + 2x²
Rearrange
(r-s)(x) = 2x²+x-6
18 - (1/2×18 + 1/3×18)
18 - (9 + 6)
18 - 15 = 3 pints left
7 3/4 - 3 = 4 3/4
the answer is 4 3/4 pints (or 5 pints if they can only buy whole ones)

Step-by-step explanation:
Using a^2-b^2 = (a-b)(a+b) you can factor the expression:
(3x^3-4y^3)(3x^3+4y^3)
