<u>Answer-</u>
<em>Strip with </em><em>2.13 ft </em><em>width can be used. </em>
<u>Solution-</u>
A club swimming pool is 21 ft wide and 41 ft long.
Hence, the perimeter of the swimming pool is
The club members want a uniform width border around the pool.
They have enough material for 264 ft²
As they will cover the perimeter of the rectangular pool, so the length of the total used strip is equal to the perimeter of the swimming pool.
Let the width of the strip is x ft
So, the total area of the used strip is,
Putting the values,
Therefore, strip with 2.13 ft width can be used.

Answer:
Growth
Step-by-step explanation:
Growth is whenever there is a larger amount and Decay is when there is less of an amount it gets smaller. In the situation more people own ferrets as pets so therefore it's going to grow and so the answer is growth.
Answer:
x = √2 + 2, -√2 + 2
Step-by-step explanation:
y = -2(x-2)² + 4
-2(x-2)² + 4 = 0 --- replace y with 0
-2(x - 2)² = -4 --- subtract 4 from both sides
(x - 2)² = 
--- divide both sides by -2
(x - 2)² = 2 --- simplify
x - 2 = +-√2 --- square root both sides
x - 2 = √2 --- split into 2 equations
x - 2 = -√2
x = √2 + 2 --- solve first equation
x = -√2 + 2 --- solve second equation
x = √2 + 2, -√2 + 2
Answer:
On 5th day and 13th day Attendance was equal for both plays and it was
231 for each .
Step-by-step explanation:
In order to find same attendance ,we need plug both equation equal
-x^2+26x+126 = 8x+191
-x^2+26x-8x+126-191 = 0
-x^2 +18x-65 =0
multiplying both sides by -1 ,we get
x^2 -18x+ 65 =0
(x-5) (x-13) =0
x =5 and x =13
On 5th day and 13th day attendance was same.
And attendance can be obtained by plugging x =5 in either of equation
y = 8(5)+191
= 40 +191
= 231
