Let's solve the problem "Write '12 more than [tex]\( r \)[/tex]' as an expression":
To express "12 more than [tex]\( r \)[/tex]," you need to think of adding 12 to the variable [tex]\( r \)[/tex].
- "More than" in mathematics typically translates to addition.
- If you have [tex]\( r \)[/tex] and you want 12 more than that, you add 12 to [tex]\( r \)[/tex].
Thus, the correct expression for "12 more than [tex]\( r \)[/tex]" is:
[tex]\[
r + 12
\][/tex]
Hence, the correct answer is:
A. [tex]\( r + 12 \)[/tex]
