None of the answers listed are correct.
3x + 11 = k
SUBTRACT 11 from both sides:
3x + 11 = k
       -11    -11
You are then left with:
3x = k-11
DIVIDE 3 by both sides:
3x/3 = k-11/3
You are then left with:
x= k-11/3
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Each of the triangles is similar, so we have ...
   3/5 = (3+x)/20
   x = 20(3/5) -3
   x = 9
__
   4/5 = (4+y)/20
   y = 20(4/5) -4
   y = 12
__
   3/5 = (3 + x + u)/60
   u = 60(3/5) -3 -9
   u = 24
__
   4/5 = (4 +y +v)/60
   v = 60(4/5) -4 -12
   v = 32
 
        
             
        
        
        
Answer:
16 meters
Step-by-step explanation:
Step 1:
They climbed 8 meters down
Then 8 meters up to get back to ground level.
Step 2:
8+8=16
 
        
             
        
        
        
okay so the answer is a. and b. since how you put them they are the same. so the answer is -4 x 8
hope this helps
 
        
                    
             
        
        
        
Take half of the coefficient of x (which is 2/5) and square it:
[ (1/2)(2/5) ]^2 = (1/5)^2 = 1/25, or 0.04
Thus, to rewrite x^2 + (2/5)x to include a perfect square trinomial,
x^2 + (2/5)x  = x^2 + (2/5)x + (1/5)^2 - (1/5)^2, or
                 (x+1/5)^2 - (1/5)^2, or (x + 1/5)^2 - 1/25
