AleksAgata [21]

Answer:

She need 7 bags to cover the garden

Step-by-step explanation:

Diameter of circular garden = 16 feet

Radius of circular garden =\frac{16}{2} = 8 feet

Area of circular garden =\pi r^2 = \frac{22}{7} \times 8^2 =200.96ft^2

30 sq.feet covered by no. of bags = 1

200.96 sq.feet covered by no. of bags = \frac{200.96}{30}=6.69

Hence She need 7 bags to cover the garden

Answer:

1. y² - 3x - 18

2. 4x² - 33x + 35

3. 12x² - 11x + 2

Step-by-step explanation:

All we do with these questions are expanding the factored binomials. Use FOIL:

1. y² + 3y - 6y - 18

y² - 3y - 18

2. 4x² - 28x - 5x + 35

4x² - 33x + 35

3. 12x² - 3x - 8x + 2

12x² - 11x + 2
