Final Answer:
a. The value of the expression glh + 2h when g = 2 andh = 6 is 36.
b. Substituting the given values, the expression becomes
, simplifying to 24 + 12 = 36.
Step-by-step explanation:
a. To evaluate the expression glh + 2h with the provided values g = 2and h = 6, substitute these values into the expression. Substituting g = 2 and h = 6, we get

b. By performing the calculations, the expression simplifies to 24 + 12, resulting in a final value of 36. This means that when g = 2 and h = 6, the expression glh + 2h equals 36.
Understanding the concept of substitution is essential in algebra. In this case, substituting the given values for g and h allows us to find the specific numeric value of the expression. This process is fundamental in solving mathematical problems, especially when dealing with variables and algebraic expressions. The final answer, 36, reflects the outcome of substituting the provided values into the given expression.
