Given the function `f(x)=2 x - 3` and the function `g(x) = 9x^2+7x + 10` determine each of the following.

Give your answer as a whole number or a simplified fraction.
Evaluate `f(6) + g(9)`      `f(6) + g(9) = `
 
Evaluate `g(8) - f(5)`      `g(8) - f(5) = `
 
Evaluate `f(2) * g(12)`  `f(2) * g(12) = `
 
Evaluate `g(11)/f(12)``g(11) / f(12) = `
