Answer:
Step-by-step explanation:
Given x^2+4x+13=0, find the complex roots.  The best approach here is to use the quadratic formula.  Note that a = 1, b = 4 and c = 13.  
Thus, the discriminant, b^2 - 4ac, is (4)^2 - 4(1)(13) = 16 - 52 = -36, and the square root of that is plus or minus i√36, or  plus or minus 6i.  
plus or minus i√
 
        
                    
             
        
        
        
8 * 3/4
Multiply 8 by 4 to get 32 then divide 32 by 3 to get 3.6 repeating
3/3 is basically 1 so its still 3.6 
3.6 is  3 3/5

Answer:
   Dimensions of original room = 12 x 12 feet.
Explanation:
  Let the size of old square room be a x a.
  New dimension = ( a+4 ) x ( a + 6 )
    We have area of the new room will be 144 square feet greater than the area of the original room.
   So,     ( a+4 ) x ( a + 6 ) = a x a + 144
               a²+10a+24= a²+144
               10a = 120
                   a = 12 feet.
  Dimensions of original room = 12 x 12 feet.
  
 
        
             
        
        
        
To find the tax rate when given the initial price of an object and the final tax value, you use the equation: $350 * X = $22.75 (where X is the sales tax rate). Then solve:
$22.75/$350 = .065
So the rate is 6.5%
