The correct answer is option A
A) Equation 1 and equation 2 have no solutions
For the equation 1
l 3x-1 l +7=2
l 3x-1 l = 2-7 =-5
The absolute value should be positive
So, there is no solution
For the equation 2
l 2x+1 l +4 = 3
l 2x+1 l = 3 - 4= -1
The absolute value should be positive
So, there is no solution
        
                    
             
        
        
        
The answer would be correct. hope that helped
        
             
        
        
        
Answer:
Z-score = 1.18
Step-by-step explanation:
The z-score measures how many standard deviations from the mean a data is
Therefore the z score is the quotient between the difference between a value and the mean and the standard deviation

Where
μ is the mean, x is a data of the population and  is the standard deviation
 is the standard deviation
In this case 

Then the z-score is

 
        
             
        
        
        
Answer:
Dimension of gymnasium= 9 units and (3x+2) units.
Step-by-step explanation:
We have been given the area of a gymnasium is  square units. We are asked to find possible dimensions of gymnasium by factoring our given expression for area of gymnasium.
 square units. We are asked to find possible dimensions of gymnasium by factoring our given expression for area of gymnasium. 
Let us factor our greatest common factor of our given expression. We can see that 9 is the GCF of our given expression.

Upon factoring out 9 from our given expression we will get, 
 
Therefore, the possible dimensions of the gymnasium will be 9 units and (3x+2) units as we will get the same area for gymnasium by multiplying these both dimensions.
