Answer :

Certainly! Let's solve the expression [tex]\(180(n-2)\)[/tex] step by step for [tex]\(n = 9\)[/tex]:

1. Step 1: Substitute [tex]\(n = 9\)[/tex] into the expression:
[tex]\[ 180(n-2) \quad \text{becomes} \quad 180(9-2) \][/tex]

2. Step 2: Evaluate the expression inside the parentheses:
[tex]\[ 9 - 2 = 7 \][/tex]
So now the expression is:
[tex]\[ 180 \times 7 \][/tex]

3. Step 3: Perform the multiplication:
[tex]\[ 180 \times 7 = 1260 \][/tex]

Therefore, the value of [tex]\(180(n-2)\)[/tex] when [tex]\(n = 9\)[/tex] is [tex]\(1260\)[/tex].
