I think you should write the equation to find perimeter such as P = 2(L + W). So the expression is 2[2(x+y) + 3(x - y)]
Simplified as 2[(2x + 2y + 3x - 3y)]
2(5x - 1y) combined like terms
10x - 2y is the expression for the perimeter of the rectangle

Answer:
<em>The value of the car after 4 years is $18,000</em>
Step-by-step explanation:
<u>Formulas</u>
The model used to compute the present value of an item that depreciates yearly is
![v=c-c.r.t](https://tex.z-dn.net/?f=v%3Dc-c.r.t)
Where v is the present value, c is the original cost, r is the rate of depreciation per year, and t is the number of years that have passed.
We are required to find the value of a car originally costing c=$30,000 that depreciated at a rate of r=0.1 per year after t= 4 years
We plug in the given data
![v=30,000-30,000\cdot 0.1\cdot 4](https://tex.z-dn.net/?f=v%3D30%2C000-30%2C000%5Ccdot%200.1%5Ccdot%204)
![v=30,000-12,000](https://tex.z-dn.net/?f=v%3D30%2C000-12%2C000)
![v=18,000](https://tex.z-dn.net/?f=v%3D18%2C000)
The value of the car after 4 years is $18,000
Set the left side as the base, the length of the base is (3-1)=2, the height is (3-0)=3, the area is 2*3=6
6 units is the answer.
