Sure, let's evaluate the expression for [tex]\( d = 2 \)[/tex].
Given:
[tex]\[ -9d \][/tex]
Substitute [tex]\( d = 2 \)[/tex] into the expression:
[tex]\[ -9 \cdot 2 \][/tex]
Now, perform the multiplication:
[tex]\[ -9 \cdot 2 = -18 \][/tex]
So, the value of the expression when [tex]\( d = 2 \)[/tex] is:
[tex]\[ -9d = -18 \][/tex]
Therefore, the result is:
[tex]\[ \boxed{-18} \][/tex]
