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.  
 
        
                    
             
        
        
        
The correct answer is A.) Obtuse.
When an angle is over 90° it is considered an obtuse angle. Any angle that measures under 90 is an acute angle.
        
             
        
        
        
C. -5 + 9 = 22 + 9 - 7 is the answer.
This is because when solved it’s : -52 = 15 which is false therefore there’s no solution.
        
             
        
        
        
Answer:
Length = 72 mm
Width = 46 mm
Ratio = 72:46 = 36:23
Step-by-step explanation:
72 and 36 both are divisible by 2. so when we divide them by two we get 36 and 23. we can divide both the sides only with the same number, but 36 and 23 have no common factors. so we leave it here and this is the answer.
 
        
             
        
        
        
Answer:
When customers wait longer for tables, they are more likely to pay higher prices.
Step-by-step explanation:
Supply/Demand relationships predict that changing one side will influence the other.  If demand exceeds capacity, suppliers can raise prices without risk of losing products sold.  In fact, total income will rise.  The restaurant may raise it's price to the point that supply meets demand.  In this case, the goal of the higher priced meals is to reduce wait times, not meals sold.  If the meals sold are all at a higher price/meal, then income rises and wait times are reduced.  What's not to like, if you own the restaurant?
