<span>Think about which perfect squares lies on the immediate left of 52 and which lies on the immediate right of 52.
49 ---- 52 ------- 64
After that, take the square roots of each of the three numbers.</span>
        
                    
             
        
        
        
Answer:
Choice A
Step-by-step explanation:
(4m^5n^2/m^2n)^3
dividing exponents = subtraction
(4m^3n)^3
4^3 = 64
(m^3 )^3 = m^3x3 = m^9
64m^9n^3
 
        
             
        
        
        
Answer: x = 1, y = -2
Step-by-step explanation:
-9x+2y=-13
x= 13/9 + 2/9y
2x-9y=20
2(13/9+2/9y)-9y=20
<em>Substitute y with -2.</em>
<em />
x= 13/9+2/9(-2)
<em>After solving you'll see that 1 is a possible solution for x.</em>
<em />
Check your answer
-9x+2y=-13
-9x1+2(-2) = -13
2x-9y=20
2x1-9(-2) = 20
-13 = -13
20 = 20
Therefore, x=1 and y=-2
 
        
             
        
        
        
27.8 × 9.6 is equal to <span>266.88</span><span>
So, the closest would be A. 280.</span>
