.394= 197/500
you can't make it a mixed number since there isn't a whole number as with an improper fraction.

Step-by-step explanation:
it clearly consists of 2 rectangles and 1 triangle (as you tried correctly to point out by drawing the separating lines).
we only need to calculate all 3 areas and add them up for the total.
the area of a rectangle is
length × width
so, in our 2 cases we have
6 × 2 = 12 km²
5 × (3 + 2 + 3) = 5×8 = 40 km²
the area of a triangle is
baseline × height / 2
in case of a right-angled triangle the 2 sides enclosing the 90° angle can be used as baseline and height. 
so, in our case
6 × (5 + 2 + (3 + 2 + 3 - 2)) / 2 = 6×(7 + 6)/2 = 3×13 = 39 km²
in total, the whole area is
12 + 40 + 39 = 91 km²
 
        
             
        
        
        
Answer:
x=2
y = 0
Step-by-step explanation:
3x + y = 6         -------------(i)
5x - 2y = 10      -------------(ii)
Multiply (i) by 2   ===>   6x +2y = 12
                      (ii)  ===>   <u> 5x - 2y =  10</u>
add   ============>    11x       = 22
                                               x = 22/11
                                               x = 2
Substitute x = 2 in (i)
        3*2 + y = 6
            6 + y = 6 
                  y =  6 - 6
                  y = 0 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Okay!
A graph representing the function :
f(x)=x(x+2)
 I will describe the graph for you!
the points on this graph are : (-3,3),(-2,0),(-1,-1),(0,0),(1,3)
the graph also creates a U shape!
