Answer:
56
Step-by-step explanation:
area of whole figure=
l×b
=20×10
=200 
also,area of small fig.
=l×b
=18×8
=144
thus area of shaded part =a of whole- a of small
 =200-144
 =56
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Slope = m = -1/4
y-intercept = b = 5
Slope intercept form = y = mx +b

 
        
             
        
        
        
Step-by-step explanation:
G(x) = 2/3 x - 6     switch x and y around and solve for y.
y = 2/3 x - 6
x = 2/3 y - 6
x + 6 = 2/3 y
3/2  x + 9 = y
