Answer:
The quadratic function representing the total area of the park and the path is
Step-by-step explanation:
The width of the rectangle is x----------(1)
Then the length = twice it's width
Length =
Length = 2x------------------(2)
Now the width along with the foot path = x +3+3 = x+9
the length along with the foot path = 2x + 3+3 = 2x +9
The total area of the park and the path =
that is
=> (2x + 9)(x+9)
=>
=>
Answer:

Answer:
Step-by-step explanation:
let CP of the article = x
at 5% gain, SP of article = x + (5/100)x = 1.05x
at 5% loss, SP of article = x - (5/100)x = 0.95x
given that 1.05x - 0.95x = 16.5
⇒ 0.1x = 16.5
⇒ x = 16.5/0.1
⇒ x = Rs. 165.
The cost price of the article is Rs. 165.
The median is 50.
The first quartile is 20, the third is 65, the difference is 45.
The answer is B cause I love mathematics.
