Step-by-step explanation:
The answer is gonna be C,which is 91.Hope this helps
Step One
Figure out the cost for 1 cartridge
Cost = 90
<u>Refund = 8 Subtract</u>
Net cost = 82
Step Two
Find the cost for 14
14 * 82 = 1148 <<<<<< Cost for 14
Solving (f×g)(x) we get ![3x^3+x^2-18x-6](https://tex.z-dn.net/?f=3x%5E3%2Bx%5E2-18x-6)
Step-by-step explanation:
We are given:
f(x)=3x+1
g(x)=x^2-6
We need to find (f×g)(x)
Solving:
![(f\times g)(x)=f(x).g(x)\\f(x).g(x)=(3x+1)(x^2-6)\\f(x).g(x)=3x(x^2-6)+1(x^2-6)\\f(x).g(x)=3x^3-18x+x^2-6\\f(x).g(x)=3x^3+x^2-18x-6](https://tex.z-dn.net/?f=%28f%5Ctimes%20g%29%28x%29%3Df%28x%29.g%28x%29%5C%5Cf%28x%29.g%28x%29%3D%283x%2B1%29%28x%5E2-6%29%5C%5Cf%28x%29.g%28x%29%3D3x%28x%5E2-6%29%2B1%28x%5E2-6%29%5C%5Cf%28x%29.g%28x%29%3D3x%5E3-18x%2Bx%5E2-6%5C%5Cf%28x%29.g%28x%29%3D3x%5E3%2Bx%5E2-18x-6)
So, Solving (f×g)(x) we get ![3x^3+x^2-18x-6](https://tex.z-dn.net/?f=3x%5E3%2Bx%5E2-18x-6)
