linn99123 · Answer

im probably a pain in the butt right

mathstudent55 · Answer

You have three things in this expression (in addition tot eh plus sign).
The number 5.
The variable b.
The number 12.

The number 12 is by itself, so it's not a coefficient.
The letter b is a variable.
The number 5 multiplies the variable b, so 5 is a coefficient.
