Question

What is the value of the expression when n = 3? 6 (n² + 2) n 16 22 30 66

Answer 1

Answer: Fourth Choice. 66

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given information

n = 3

Given expression

6 (n² + 2)

Substitute values into the expression

=6 (3² + 2)

Simplify exponents

=6 (9 + 2)

Simplify values in the parentheses

=6 (11)

Simplify by multiplication

=$\boxed{66}$

Hope this helps!! :)
