A rectangular city park is going to be expanded to 2.5 times its current size. The city will then install fencing around the park to protect the new playground, ball fields, and walking trails. If the current park has a perimeter of 2.5 miles; how much fencing will be needed for the expanded park?

$35.59 in pounds

step-by-step explanation:

an altitude of 15,000 feet

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
