0.888
Step-by-step explanation:
Answer:
The length of the subway on the map is 
Step-by-step explanation:
we know that
The scale on the map is equal to the length of the subway on the map divided by the length of the subway in the actual
so
Let
z------> the scale on the map
x------> the length of the subway on the map
y------> the length of the subway in the actual
In this problem we have
substitute and solve for x
Answer:
S.p = (100x$680)/35=$1942.5
Step-by-step explanation:
The sum of the area of these three rectangles will be 3x² + 20x.
<h3>What is the area of the rectangle?</h3>
Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W square units
The lengths and the widths of the following three rectangles are labeled.
The area of the first rectangle will be
A₁ = x · x
A₁ = x² square units
The area of the second rectangle will be
A₂ = 20 · x
A₂ = 20x
The area of the third rectangle will be
A₃ = 2x · x
A₃ = 2x²
Then the sum of the area of these three rectangles will be
A = A₁ + A₂ + A₃
A = x² + 20x + 2x²
A = 3x² + 20x
Thus, the sum of the area of these three rectangles will be 3x² + 20x.
