Answer:
The dimensions of the pool are:
Width: 8.944 feet
Length: 17.888 feet
Step-by-step explanation:
From Geometry, the area of a rectangle (
), measured in square feet, is determined by the following equations:
(1)
Where:
- Width, measured in feet.
- Length, measured in feet.
If we know that 
, 
and 
, then we get the following second order polynomial:
(1)
And we solve the expression for 
:
Then, the dimensions of the pool are, respectively:
and 
The number of songs is x so twice the nb of songs is 2x and 3 fewer than gives -3 so we obtain 2x-3
Answer:
Each pair of shoes cost 26$
Step-by-step explanation:
<em>find the total cost for shirts</em>
2 shirts * 12$ each
2 * 12 = 24
they spent 24$ on shirts
<em>create an equation</em>
24$ shirts + x$ shoes = 76$
24 + x = 76
<em>subtract 24 from both sides of the equation</em>
24 + x - 24 = 76 - 24
x = 76 - 24
x = 52
they bought 2 pairs of shoes that cost the same amount
52 = x + x
52 = 2x
<em>divide both sides of the equation</em>
52/2 = 2x/2
52/2 = x
26 = x
each pair of shoes cost 26$
Answer:
