Answer:
-0.55 + 0.53a 
Step-by-step explanation:
               -0.55 – 0.47a + a
  To find an expression equivalent to this, we must simplify the equation to a reasonable extent;
          -0.55 – 0.47a + a
       = -0.55 + 0.53a 
       = 0.53a - 0.55
The expression equivalent to the given one is -0.55 + 0.53a  or 0.53a - 0.55
 
        
             
        
        
        
I'm not entirely sure what you're looking for, but here are your options. If you need a perfect square, I'd go for the 12 and 12, but I hope this helps?
 
        
             
        
        
        
Answer:
   $420,000
Step-by-step explanation:
The added percentage can be turned into a multiplier to make the problem easier.
   value + 12%×value = value(1 +0.12) = 1.12×value
   1.12×$375,000 = $420,000
It is $420,000 now.
 
        
             
        
        
        
X, y - the numbers
The numbers multiply to 100.

The numbers add up to -29.

Substitute -x-29 for y in the first equation:

The numbers are 
-4 and 
-25.
 
        
        
        
Answer:
2^5 + 4^3 – 6x + 3
Step-by-step explanation:
Order the numbers by decreasing exponents. Start with the 2^5, since it has an exponent of 5. Next is the 4^3 since it has an exponent of 3. After that is -6x since it has an exponent of 1. 3 is last because it has an exponent of 1 and it has no variables attached.
