Answer:
No.
Step-by-step explanation:
Notice that 72 can be written as 8 * 9.
4√72 = 4(√8)(√9) = 4(√8)(3) = 12√8.
Hence the answer is No.
 
        
                    
             
        
        
        
Answer:
 Y=2×+13
Step-by-step explanation:
2×+3=0
2×=0-3 
you use 3 to divide it self =×
×=3
 
        
             
        
        
        
Distribute the 1/4:
1/4(16x) + 1/4(20) - 7x
Do the multiplication: 
1/4(16x) = 16x/4 = 4x 
1/4 (20) = 20/4 = 5
Now you have: 
4x + 5 - 7x = 0 
Combine like terms (4x and -7x): 
-3x + 5 = 0 
Subtract 5 from both sides: 
-3x = -5 
Divide by -3:
x = -5/-3 = 5/3
Answer: 
x= 5/3
