write the worlds as an algebraic expression. the width plus twelve. how do i do it?

• : Answer: X + 12
  
  Reason/Explanation:
  It's asking us to write the words as an algebraic expression. "The width plus twelve." For starters, we don't know what the width is, so we use a variable, X. Now we add 12. So we use X + 12. The width is X, plus twelve.
