Answer: None of these answers are correct; tell this to your teacher. The 1st answer is closest to correct.
Step-by-step explanation:
The second and fourth answers are not viable because expanding them would result in x^3 which is not in the original equation.
1. 5x(x+3)-2(x+3)
5x^2+13x-6, This answer is closest to correct and may be correct in the case of a typo.
3. 5x(x-3)-2(x-3) ; Expand
5x^2-15x - 2x +6
5x^2-17x+6
The notation V(r) actually gives the volume of air inside the basketball. V(r) is volume as a function of radius, r It can be written as: V(r) = 4/3πr³ So, for any value of r, we can get the volume V. For, example, when r = 7cm we can say; V(7) = 4/3 x 22/7 x 7³ = 1437.33 cm³
