Answer:
length = 78 m , width = 27 m
Step-by-step explanation:
let w represent width then length l = 3w - 3
the perimeter (P) is calculated as
P = 2l + 2w = 210 , substitute values
2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side
6w - 6 + 2w = 210
8w - 6 = 210 ( add 6 to both sides )
8w = 216 ( divide both sides by 8 )
w = 27 and l = 3(27) - 3 = 81 - 3 = 78
Then length = 78 m and width = 27 m
 
        
             
        
        
        
600 g
Explanation:
Since 1 kilogram =1000 grams 
Therefore 3 grams= 3000 grams 
Now divide it with 5 partners 
3000 divided by 5=600 grams 
Each person will get 600 grams of gold dust

Answer:
C)	The parabola is narrower and reflected across the x-axis.	
Step-by-step explanation:
The original parabola has equation:

The transformed parabola has equation 

How wide the graph is can be determined by the absolute value of the coefficient.
The smaller the absolute value of the coefficient, the wider the graph.
Since 

The original graph is wider than the transformed graph.
Also the negative factor tells us there is a reflection in the x-axis.
 
        
             
        
        
        
7/12 because it would come out to be 21/36, and the simplified version of that is 7/12<span />
