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

I think it’s 28.35

54/100 x 5 = 2.7
54 + 2.7 = 56.7
56.7/100 x 50 = 28.35
56.7 -28.35 = 28.35
