Answer:
length and width are x + 6 and 5x - 7y
Step-by-step explanation:
5x² + 30x - 7xy - 42y
= 5x(x + 6) - 7y(x + 6)
= (x + 6)(5x - 7y)
so
length and width are x + 6 and 5x - 7y
 
        
             
        
        
        
Answer=360
60%=.6
600*.6=360
_______________________________________________
another way to solve the question
  60        x
____=_____
100     600
cross multiply
100x=36000
divide both sides by 100
x=360
        
                    
             
        
        
        
Answer:
Expression is '98 divided by 0.005' i.e.  .
.
Step-by-step explanation:
We have that,
The quotient of 8 divided by 0.001 is given by,
 =
 =  = 8000.
 = 8000.
It is required to find a division expression having quotient greater than 8000.
Let us consider,
'98 divided by 0.005'
i.e. 
i.e. 
i.e. 98 × 200
i.e. 19,600
Thus, the get the quotient of the new expression 19,600 > 8000.
Hence, the required expression is '98 divided by 0.005' i.e.  .
.
 
        
             
        
        
        
Answer:
Calculating 75% of a number is the same as calculating 25% less
Step-by-step explanation:
.75*100=75
.25*100=25
100-25=75
 
        
             
        
        
        
Answer:
28
Step-by-step explanation:
x equals 1 
y equals 11 
you would plug the numbers in 
(1)6 plus (11)2 which if you multiply them
6 plus 22 would give you 28
