Answer:
Step-by-step explanation:
We first calculate the area of the entire pool and the side walk.
Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet
Thus the area of the entire pool and the side walk is obtained as follows:

Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.
Thus the area of the pool is given by:

Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:
Answer:
Because D = 24 and this is bigger then zero, there are two real solutions.
Step-by-step explanation:
if the discriminant (D) has a positive number, then there are two real solutions. So let's calculate the value of D.
-2x² + 3 = 0
a = -2
b = 0
c = 3
D = b² - 4 * a * c
Substitute the values of a, b and c and you get...
D = 0² - 4 * -2 * 3
D = 24
Because D = 24 and this is bigger then zero, there are two real solutions.
