Answer: Option A
Take not that this is a square bulletin board thus area = Length Times Base. Notice how it says its a square as well? thus telling us that each side is of equal length
Squaring the value N would give us the value of the one side of the board

Answer:  A) 46</h3>
Explanation:
The angles shown are same side interior angles.
For line L to be parallel to line M, the same side interior angles must be supplementary, or they must add to 180.
28+(3x+14) = 180
28+3x+14 = 180
3x+42 = 180
3x = 180-42
3x = 138
x = 138/3
x = 46

Answer:
   10)  C 4/9
   11)  B 24
Step-by-step explanation:
10) The area ratio is the square of the ratio of side lengths. The ratio of side lengths is ...
   RS/LM = 6/9 = 2/3
Then the area ratio is ...
   (2/3)² = 4/9
__
11) Using the result of question 10, the area of ∆RST is ...
   (4/9)(54 in²) = 24 in²
 
        
             
        
        
        
Let us denote the number of tiles by 

.
In the first store, if Darin bought 

 tiles, he would need to spend:                        

 (measured in $)
In the second store, if Darin bought 

 tiles, he would need to spend:                        

 (measured in $)
For the cost to be the same at both stores, it means (measured in $)                                           

Moving 

 over to the left hand side and changing signs:                                            
 
                                             
                                             
                                            
 tiles
Let's check. If he buys 60 tiles in the first store, he spends:
                              $0.79×60 + $24 = $47.40 + $24 = $71.40
If he buys 60 tiles in the second store, he spends:
                                               $1.19×60 = $71.40
∴
 Darin needs to buy 60 tiles for the cost to be the same at both stores.
