$\text{Combine like terms:}\\\\(-3y^2 - 5y- 2) +(-7y^2- 5y + 2)\\\\-3y^2 - 5y- 2 -7y^2- 5y + 2\\\\-10y^2-5y-5y-2+2\\\\-10y^2-10y-2+2\\\\\boxed{-10y^2-10y}$

Mathematics

50.27 cm²

Step-by-step explanation:

Subtract the area of the smaller circle from the area of the larger circle

The area of a circle = πr² ( r is the radius )

area = π × 5² - π × 3² = 25π - 9π = 16π ≈ 50.27 cm² ( nearest hundredth )
