Answer:
x < -12
Step-by-step explanation:
Given the inequality
-2(x + 3) < 6 - x 
Expand
-2x - 6 < 6 - x
Collect the like terms;
-2x + x < 6 + 6
-x < 12
Multiply through by -1
-1(-x) < -1(12)
x < -12
 
        
             
        
        
        
Just divide both sides by 2 because you want to do the opposite operation, to isolate x so if you do you get 80 so x = 80
        
                    
             
        
        
        
15, because angle L and N are equal, 3x=x+10 so x=5, plugging it in, we get that MN is 15
        
                    
             
        
        
        
Answer:
d = sqrt(17)
Step-by-step explanation:
d = sqrt( x2 - x1)^2 + (y2 - y1)^2  )
d = sqrt( (4 - 5)^2 + (-3 - 1)^2 )
d = sqrt( (-1)^2 + (-4)^2  )
d = sqrt ( 1 + 16)
d = sqrt(17)
