Answer:

Step-by-step explanation:

Part A:  A coefficient is a number stuck to a variable (a variable is the letter).  Our coefficients are 20 and 9

Part B:  There are 2 terms in our expression.  A term is a combination of numbers and letters stuck together by multiplication, and terms are separated by addition or subtraction.

Part C:  The term that is the expression representing the total earned from trimming is 9y, since he earns $9 for every hedge he trims.  The 20 goes with the lawns he mows.
