Recalling function notation, we want x to be w. Therefore, if f(x) = (3x + 5) / 2, find f(w).

The answer would be 13.5 minutes.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
