Which student's expression has a coefficient of 1 when simplified? Will choose brainliest. Plz include explanation.

Answer:

Step-by-step explanation:
When simplifiying Nate's expression, you will distribute a 1 to each of the values in the parentheses. This will make 7 + 1x + 1, which can simplify down to 1x + 8. A coefficient is the number attatched to a variable, making 1 the coefficient in this expression.
