From top to bottom: 16, 5, 28. Please give me 'brainliest answer?
        
                    
             
        
        
        
Never seen the exact thing before
But if I’m not mistaken
a should be the number before x^2
b is before x
c is the last number
including the negative sign!
        
             
        
        
        
Answer:
See below
Step-by-step explanation:
4(x + 5) = 9x + 4x − 34
4x + 20 = 9x + 4x − 34   [Distributive]
4x + 20 =  13x − 34         {Combine Like Terms]
4x - 13x + 20 = 13x - 13x − 34  [Subtractive:  -13x both sides]
-5x + 20 = - 34            [Combine Like Terms]
-5x + 20 - 20 = -34 - 20     [Subtractive:  - 20 both sides]
-5x  = -54               [Combine Like Terms]
x = -54/-5             [Division Property:  divide both sides by -5]
x =  - 10 4/5            
 
        
             
        
        
        
Simplify the following:
((8 x^3 y^2 a^2 b^4)/4)^(-2)
8/4 = (4×2)/4 = 2:
(2 x^3 y^2 a^2 b^4)^(-2)
Multiply each exponent in 2 x^3 y^2 a^2 b^4 by -2:
(x^(-2×3) y^(-2×2) a^(-2×2) b^(-2×4))/(2^2)
-2×3 = -6:
(x^(-6) y^(-2×2) a^(-2×2) b^(-2×4))/2^2
-2×2 = -4:
(y^(-4) a^(-2×2) b^(-2×4))/(2^2 x^6)
-2×2 = -4:
(a^(-4) b^(-2×4))/(2^2 x^6 y^4)
-2×4 = -8:
b^(-8)/(2^2 x^6 y^4 a^4)
2^2 = 4:
Answer: 1/(4 x^6 y^4 a^4 b^8) thus the answer is A
