Final answer:
The student must translate the verbal expression "six times the sum of a number cubed and two" into an algebraic one, which is 6(n^3 + 2). When evaluated with n = 3, the result is 174.
Step-by-step explanation:
The student's task involves writing an algebraic expression based on a word problem and evaluating the expression for a given value of n. The expression given is "six times the sum of a number cubed and two." We can translate this into mathematical notation as 6(n3 + 2). To evaluate when n = 3, we substitute 3 for n and simplify using the order of operations:
Next, we add 2 to the cubed value: 27 + 2 = 29.
Finally, we multiply by 6: 6 × 29 = 174.
The value of the expression when n = 3 is 174. Hence, the correct choice is "The value of the expression is 174."
