Question

Find 9n + 2(n+5) +3 when n = 2.

Answer 1

Explanation:

To evaluate the expression 9n + 2(n+5) +3 when n = 2, we substitute the value of n into the expression and simplify it step by step.

First, we substitute n with 2:

9(2) + 2(2+5) + 3

Next, we simplify the expression inside the parentheses:

9(2) + 2(7) + 3

Now, we perform the multiplication:

18 + 14 + 3

Next, we perform the addition:

18 + 14 + 3 = 35

Therefore, when n = 2, the expression 9n + 2(n+5) +3 evaluates to 35.
