Answer:
length: 23 m; width: 11 m.
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of its length and width, so that sum is 34 m. Then you can write two equations in length and width:
l + w = 34
l - w = 12
Adding these together gives you ...
2l = 46
l = 23 . . . . . . divide by 2
Then the width is
w = 23 -12 = 11
The length and width are 23 m and 11 m, respectively.
The final value of the truck after depreciation and the number of years you own the truck are the two variables in this problem.
The dependent variable is the final value of truck after depreciation and the independent variable is the number of years you own the truck.
We are given that the initial value of truck is $12,400 and depreciation value per year is $820.
We know that,
Final Value = Initial Value - Depreciation value per year * Number of years
Let Final value be y
Let the number of years be x.
Hence, the equation will be:-
y = 12400 - 820*x
y = 12400-820x
We can clearly see from the equation that the final value of truck will depend on the number of years you own the truck.
