Solve the following radical equations. 5√x−6=−20 Answer choices: x=−10 x=10 x=22 No solution

myrzilka [38]

Answer:

Step-by-step explanation:

$5 \sqrt{x} -6=-20$

1. You divide 5 by both sides, which will give you $\sqrt{x-6}=-4$

2. You then square both sides of the equation, which will give you $x-6=16$

3. Since the equation is now one-step, you then do GEMDAS and you will get x=22

Jane has a circular garden with a diameter of 16 feet if one bag of fertilizer covers 30 ft.² how many bags will she need to cov

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
