Answer:
The answer to your question is letter C. 7y³ + 7n²y² - 22y²
Step-by-step explanation:
y²(4y + 7n² + 2) - 3y² (-y + 8)
Multiply
4y³ + 7n²y² + 2y² + 3y³ - 24y²
Use the associative property for like terms
(4y³ + 3y³) + (2y² - 24y²) + 7n²y²
Simplify like terms
7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²
