Answer:
X = 1
Step-by-step explanation:
2x^2 + x - 1 = 2
2x^2 + x - 3 = 0
2x^2 + 3x -2x - 3 = 0
x(2x+3) -1 ( 2x+3) = 0
(x-1) (2x+3) = 0
x-1=0
x=1
2x+3=0
2x=-3
x=-3/2.
You never put in what the question was.
Answer:
Step-by-step explanation:

Answer:
<h2>radius = 9.77 yards</h2>
Step-by-step explanation:
Since the pool is circular
Area of a circle = πr²
where
r is the radius
From the question
Area = 300 square yards
To find the radius substitute the value of the area into the above formula and solve for the radius
That's
300 = πr²
Divide both sides by π
We have

Find the square root of both sides
That's

r = 9.7720502
We have the final answer as
<h3>radius = 9.77 yards</h3>

Answer
$168.75
Step-by-step explanation:
$22.50 per hour meaning every hour she gets 22.50
half an hour would be half the money so
22.50 * 7 = 157.50
22.50/2 = 11.25
157.50 + 11.25 = 168.75
168.75 is the answer
