The perimeter of the sandbox is 60 ft.
5x5=25
Two sides = 25, so 25+25 = 50.
Two other sides = 5, so 5+5=10
50+10 = 60, and that is the correct answer.

Answer:
B. 4 
Step-by-step explanation:
The sign  means greater than or equal to
 means greater than or equal to 
The sign > just means greater than 
4 is a solution for x  4, because 4 is equal to 4, but not a solution for x>4, because 4 is not greater than 4
4, because 4 is equal to 4, but not a solution for x>4, because 4 is not greater than 4 
Hope this helps! :)
 
        
             
        
        
        
Answer:
y= -x(x+2)(x-1)².
Step-by-step explanation:
the graph and equation is in the attached picture.
The zeros of function y are: -2; 0 and 1 - they help to determine the required equation.
 
        
             
        
        
        
Answer:
The answers to the first question are A,C,D
The answer to the second question is YZ=16
Step-by-step explanation:
(1st Question)
Since <K and <M Are equal, and both <L's are equal, KL and ML are congruent (Answer choice) because of the ASA postulate. 
You need to create the following equation to find the length of KN and MN 7x-4=5x+12
(Get the "x" variable to one side)
2x-4=12
(Isolate the variable)(Remove the 4)
2x=16
(Divide the 2 by itself to remove it from the x, remember to divide both sides by 2)
x=8 (Answer Choice)
Plug in the x value into each equation
KN= 7(8)-4
KN= 56-4
KN= 52
MN= 5(8)+12
MN= 40+12
MN= 52 (Answer Choice)
MN=KN 
(Second Question)
Since XWY(20) is half of XWZ(40), ZWY also equals 20. 
This now proves the triangle is congruent by the AAS postulate.
Since the triangles are congruent, if XY = 16, YZ also equals 16.
