Answer:
27/100
Step-by-step explanation:
Put the argument value where the variable is, then evaluate.
For f(x), you want f(2).
f(2) = 2² + 1 = 4+1 = 5
For g(x), you want g(1).
g(1) = 3·1 +1 = 4
For [f(2) - g(1)] you want the difference of the above values.
[f(2) - g(1)] = [5 - 4] = 1
The weight seems like most accurate to me, even thought you didn't show me what type of measurement he took.
I guess 52inches as volume of a prism=Base area x Height
