Answer: The TV is 48 inches wide.
Step-by-step explanation: To find the solution to this equation we must use the Pythagorean theorem. The Py. Theo. is basically the formula : 
a^2 + b^2 = c^2    You say this as "A squared plus b squared equals c squared" 
To use this formula you must plug in the given values of a and b, to find c. A and b represent the two bases of the triangle, while c is the hypotenuse. In this equation we already have the value of c and a. We need to find b, but in order to do that we use a different formula. We use : c^2 - a^2 = b^2
See : 
52^2 - 20^2 = b^2       *The ^2 means "to the power of" aka an exponent*
2704 - 400 = b^2     *When dealing with ^2, all you do is multiply the number by itself*
2304 = b^2      *Next, we find the square root of our current number.*
48 = b     
*Another way to solve this equation is to memorize all the Pythagorean Triples. With that knowledge, you wont even need to use the formula because you will already know all three values. I hope this helped you understand :)
 
        
             
        
        
        
The answer is 19.. substitute -1 into the function whenever you see x put -1 there. This implies that 3+16 =19
        
             
        
        
        
Answer:
the answer is 224 decimeters 
Step-by-step explanation:
first you need to draw a box than label the length and with which is 14 by 16 and then you can use the formula A=L*W. Know you can plug the numbers in 14*16 which equals 224 and that would be your answer
