The range of a log is all real numbers, only the domain is limited. Therefore the answer is +infinity to -infinity.
        
             
        
        
        
7 - 4 ( d - 3) = 23
7 - 4d + 12 = 23
Subtract 12 from both sides,
7 - 4d = 11
Subtract 7 to both sides
- 4d = 4
Divide -4 to both sides
d = -1
 
        
                    
             
        
        
        
1.001 is the smallest :)))
        
             
        
        
        
Step-by-step explanation:
1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....
= Solution , 
Length ( L ) = ? 
breadth ( b ) = 10xy cm 
area ( a ) = ( 30x² + 20xy ) 
Now , 
area ( a ) = l × b 
or, ( 30x²y + 20xy ) = L × 10xy cm 



2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
= Solution, 


The product of 3x and 4y = 6xy 
= 6x - 4xy 

hope it helped !!!!
