Area is equal to length times width, so we can use this over here:

Area = lw
Area = (x+7)(x+1)
Area = x^2+x+7x+7
Area = x^2+8x+7

A=w•l
w=x+1

Sam purchased a laptop at $800 each year the laptop will lose 12% of its value each year what would it be the approximate value of Sam's laptop after 7 years

Answers

Answer:

$326.94

Step-by-step explanation:

For this equation you are going to do a exponential function, since we are working with percents. To do this you will make the equation

(starting price)x(1-percent)^(t) t=years

which will create the equation

800(0.88)^t

You will then plug in t=7

800(0.88)^7 =

800(0.409) =

326.94 (you will cut it off at the hundredth position because it is working with money)
