Answer:  16.97
<u>Step-by-step explanation:</u>
To find the distance from W to X, you can use the distance formula ...or... draw a right triangle using W and X as the vertices and use Pythagorean Theorem to find the hypotenuse. I will solve using the latter.
The y-distance from W to X is 12.
The x-distance from W to X is 12.
hypotenuse² = 12² + 12²
                       = 144 + 144
                       = 288
 hypotenuse = 
                      = 16.97
 
        
             
        
        
        
I cant see the picture i can’t help sorry
        
             
        
        
        
You combine the like terms to get
2s^2y^2-4a^2sy+2a^4
        
             
        
        
        
I’m sorry I don’t know the answer to that but maybe if you go in quizlet you can find the answer.
