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].
