Answer:
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.
