Answer:
Step-by-step explanation:
first we will break the parts of the question down: 
d= distance
t= time
function: d=t(60)
the <em>independent </em>variable is t, time, because the (distance) that the car travels <u>depends  </u> on how long the car has been traveling for (time) meaning that the dependent value is distance. 
A table we can create with 5 coordinate pairs is: 
(time)        (distance)
1 hr            60miles
2 hr           120 miles
3 hr          180 miles
4 hr            240 miles
5 hr           300 miles 
(to graph the coordinate pairs, you can graph the points listed in the table. the time value represents the x value since it is the independent variable, and the y value will be the distance values since it is dependent.)

As per the problem,
Rhonda bought a new laptop for $800.
The laptop depreciates, or loses, 20% of its value each year.
The value of the laptop at a later time can be found using the formula 

Here we have 
P=$800
r=20%=0.20
t=2 years
Substitute the values in equation (1) we get

The laptop be worth in two years will be $512.
 
        
             
        
        
        
Let the length equal x
Then the width would be 4x + 8 (8 feet more than 4 times the length)
Area = length x width:
5,472 = x * 4x+ 8
Simplify:
5472 = 4x^2 + 8x
Subtract 5472 from both sides:
4 x^2 + 8x - 5472 = 0
Use the quadratic formula to solve for x.
X = 36
Now you know the length is 36 feet
The width = 4(36) + 8 = 152 feet
Now find the perimeter: 152 + 152 + 36 + 36 = 376 feet.
The answer is B. 376
