For the first blank where it asks for the perimeter, the perimeter is all the outside sides of a shape added up. So, 6 + 1 + 2 + 4 + 4 + 5 = 22.
For the second blank, you just multiply the entire perimeter by 5, so, 22 times 5=110.
For the third blank, it is basically the same as the previous question. The answer is 5.
For the fourth blank, it is the same perimeter as the first blank, but instead of centimeters, it is in k. So, 22k.
Hope this helped! :)
        
                    
             
        
        
        
Step-by-step explanation:
4x-0=12
4x=12divide both sides by 4 
x=3
 
        
             
        
        
        
%error=100(estimate-actual)/actual
%e=100(50-40)/40=25%
can't see the whole question but...
40(60/100)=24
so 24/40=3/5 carry a phone.
24 students carry a phone.
        
             
        
        
        
W=166 degrees
okay so the total measure of the angles should be 360 so you gotta do 86+86+72+w=360
86+86+72=244
360-244=116
