Sarah's expression is correct because for every hour you get 9 dollars so 9(1) is 9 dollars for one hour. Then for two Hours it would be 9(2) which equals 18.
Answer:
C
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
- 2x(- 4x - 3) - 9y²(- 4x - 3) ← distribute both parenthesis
= 8x² + 6x + 36xy² + 27y² → C
Add 3 and 9 together divided by 2 ....u should get 6
