Answer:
38.957625 US$
Step-by-step explanation:
38.957625 US$
 
        
                    
             
        
        
        
A = 864
w = 2/3l
A = lw
Plug in what we know:
864 = l(2/3l)
Multiply:
864 = 2/3l^2
Divide 2/3 to both sides or multiply by its reciprocal, 3/2:
864 * 3/2 = l^2
2592/2 = l^2
1296 = l^2
Find the square root of both sides:
l = 36
So the length of the basement is 36 feet.
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
<u>Simplify the numerator:</u>
- 1/x² + 2/y = 
- y/(x²y) + 2x²/(x²y) =
- (2x² + y)/(x²y)
<u>Simplify the denominator:</u>
- 5/x - 6/y² = 
- 5y²/(xy²) - 6x/(xy²) = 
- (5y² - 6x) / (xy²)
<u>Simplify the fraction:</u>
- (2x² + y)/(x²y) ÷ (5y² - 6x) / (xy²) = 
- (2x² + y)/(x²y) × xy² / (5y² - 6x) =
- y(2x² + y) / x(5y² - 6x) 
 
        
             
        
        
        
Answer:
therefore the side of the square is 2x + 5.
Step-by-step explanation:
i) let the side of the square be a
ii) therefore the perimeter of the square = 4a
iii) therefore 4a = 8x + 20
iv) therefore a  = 2x + 5
therefore the side of the square is 2x + 5.
