<span>The length of a rectangle is three feet shorter than twice its width. If the are of a rectangle is 170ft^2, what is the length of the rectangle? 
...
let width be x feet
length = 2x-3
Area = 170 ft^2
...
Area = L*W
x(2x-3)=170

2x^2-3x=170
2x^2-3x-170 =0
2x^2-20x+17x-170=0
2x(x-10)+17(x-10)=0
(x-10)(2x+17)=0
Take positive value x= 10 feetthe width
Length = 20-3 = 17 feet

Modify the values.</span>

Roberto listed his assets and liabilities on a personal balance sheet.
mixer [17]
To see the effect on Robertos balance sheet, we will first have to get the total assets and liabilities
Total assets = cash+ investment+ house + car
Total liabilities= credit card + personal loan + mortgage  + car loan
Substituting the values, we will get
Total asset =$166000
Total liabilities =$1010000
Difference= $844000
To pay off car loan, he uses his investment
Total asset = $166000-5000
                   =$161000
Total liabilities= $1010000-5000
                        =$1005000
Difference=$844000
Therefore the answer is letter C, the difference between asset and liability will remain the same.
