Final answer:
The expression that represents the value of g when j = h and k = m is D. gu.
Step-by-step explanation:
The expression that represents the value of g when j = h and k = m is D. gu.
We are given that j = h and k = m. From these equations, we can substitute the values of h and m into the expression for g.
Therefore, the correct expression is D. gu.
