Step-by-step explanation:
To find the cost of the entire fence, we need to first determine the lawn's length before calculating its perimeter.
Area of rectangular lawn = (formula for the area of a rectangle)
feet
Now that we have the lawn's length and width, we can calculate the perimeter:
Perimeter (formula for the perimeter of a rectangle)
feet
Since each foot of lawn costs $2, then the cost of the entire fence will be:
∴ The entire fence costs .

Answer:
y = (x + 1) (x - 1) (x - 3)
Use the distributive property to multiply x+1 by x-1 and combine like terms.
y = (x² - 1) (x - 3)
Use the distributive property to multiply x² - 1 by x - 3.
<u>y = x³ - 3x² - x + 3.</u>
