How is a coefficient similar to and different from a variable term?
Answers will vary. What is in a variable term, it included the variable and the "amount of mysteries." Like, 4x is a variable term because it tells you how many mysteries/variables there are. A coefficient is simply the number of mysteries without the variable itself, so in this case it would just be 4.
