The area of the trench is 5 m²
Step-by-step explanation:
Tanya has a garden with a trench around it
- The garden is a rectangle with length 2
m and width 2 m
- The trench and garden together with length 3
We need to find the area of the trench
The area of the trench is the difference between the area of the garden with the trench and the area of the garden
The formula of the area of a rectangle is A = length × width
∵ The garden is a rectangle with length 2 m and width 2 m
∴ Length = 2 m
∴ Width = 2 m
Find the area of the garden
∴ A = 2 × 2 = 5 m²
∵ The trench and garden together with length 3 m and width 3 m
∴ Length = 3 m
∴ Width = 3 m
Find the area of the garden with the trench
∴ A = 3 × 3 = 10
The area of the trench = area of the garden with the trench - area of the garden
∴ The area of the trench = 10 - 5 = 5
The area of the trench is 5 m²

Answer:
see the explanation
Step-by-step explanation:
we know that
A linear function in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept
x is the independent variable or input value
f(x) is the dependent variable or output value
In this problem we have
where
m is the number of miles
f(m) is the cab company's fare in dollars
we have that
In this context
<em>Slope</em>
The slope or unit rate is equal to the cost per mile for the riders trip
The slope is $3 per mile
<em>Y-intercept</em>
The y-intercept is the cost of the riders trip when the number of miles is equal to zero, also is called the initial value.
The y-intercept is $5
