Your new computer cost $1500 but it depreciates in value by about 18% each year. Write an equation that would indicate the value of the computer at x years.

2+348)(27252)

Step-by-step explanation:

It is this because it’s da right answer

The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5). 
Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)

1. Perimeter(as sum) = a+b+c
                                    =  (x-4.5)+(x-4.5)+(x-4.5)
                                    = x+x+x-4.5-4.5-4.5
                                    = 3x - 13.5
2. Perimeter (as product) = 3×a    
                                     = 3×(x-4.5)
                                     = 3×x - 3×4.5
                                     = 3x - 13.5
(you can write 3×b or 3×c also as a=b=c.)

Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.
