Given the function `f(x)=3 x - 4` and the function `g(x) = 3x^2+8x + 4` determine each of the following.

Give your answer as a whole number or a simplified fraction.
Evaluate `f(10) + g(11)`      `f(10) + g(11) = `
 
Evaluate `g(12) - f(9)`      `g(12) - f(9) = `
 
Evaluate `f(6) * g(4)`  `f(6) * g(4) = `
 
Evaluate `g(2)/f(12)``g(2) / f(12) = `
