Answer:
Natural Numbers, Whole Numbers, and Integers are rational numbers. 
Example: {1, 2, 3, -1, -2, -3}
Numbers with repeating decimals and terminating decimals are also rational.
Example: {2.34343434..., 3.45}
If a square root makes a perfect square, then it is rational. 
Example: {√16, √100}
Hope this helps. 
 
        
             
        
        
        
Answer:
x=133
Step-by-step explanation:
Given: m║n
This means that 147 and x+14 are <em>alternate exterior angles</em>. This also means that they are equivalent. We can use this information to set up an equation:
x+14=147
Subtract 14 from both sides to isolate x
x=133
 
        
             
        
        
        
Answer:
the x should be 10x7-(9x6)
Step-by-step explanation:
because it should be 10x7-(4+30)
 
        
                    
             
        
        
        
If you plot the points you will find you have to use the distance formula. Pick out 2 pairs label them (x1,y1) (x2,y2) then plug it into the distance formula. The repeat for the other sides. So you should get (2,5) (4,3) plug into distance formula what is get it distance between those two points, then (4,3) (-2,-1) plug into distance formula to get an answer, lastly (-2,-1) (2,5) plug in. Now you have three answers add all together and here is your perimeter of a triangle.
