Answer:
10 times 
Step-by-step explanation:
5 gallons = 20 quarts 
20 quarts / 2 quarts = 10 
 
        
             
        
        
        
We just need to get the perimeter of the backyard.
Whole rectangle: length = 7ft ; width = 5 ft
Perimeter = 2(7+5) = 2(12) = 24 ft
        
             
        
        
        
Answer:
   6x -5y = 6
Step-by-step explanation:
You can use the 2-point form of the equation of a line to find it.
   y = (y2 -y1)/(x2 -x1)(x -x1) +y1
   y = (6-0)/(6-1)(x -1) +0
   y = 6/5(x -1) . . . . . . point-slope form
   y = (6/5)x -6/5 . . . . slope-intercept form
   5y = 6x -6
   6x -5y = 6 . . . . . . . standard form
 
        
             
        
        
        

Explanation
![9-\sqrt[]{-64}](https://tex.z-dn.net/?f=9-%5Csqrt%5B%5D%7B-64%7D)
Step 1
Let's remember that
A complex number is an object of the form

where a and b are real numbers and
![\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20i%5E2%3D-1%20%5C%5C%20i%3D%5Csqrt%5B%5D%7B-1%7D%20%5Cend%7Bgathered%7D)
so
![\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%209-%5Csqrt%5B%5D%7B-64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%5Ccdot64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%7D%5Csqrt%5B%5D%7B64%7D%20%5C%5C%209-8%5Csqrt%5B%5D%7B-1%7D%20%5C%5C%209-8i%20%5Cend%7Bgathered%7D)
therefore, the answer is 

I hope this helps you
