The same as the greatest number that can be written 
with 10 binary bits:  <u>1,024</u>
        
                    
             
        
        
        
I think that would be a right angle triangle or is that not what it is meaning
        
                    
             
        
        
        
In any equation there is a variable (usually x). In a quadratic equation there is a lot involved.
-B (+or-) sqrt of b^2 - 4 x A x C
________________________  divide it by
               2 x A
                                                   There is usually an original equation that looks like:  Ax^2 + Bx + C = 0    Use the variables from the equation to the left to fill the upper equation.  (You can also look up a better formula if confused).
        
             
        
        
        
Solution
-6x - 3y = 9              Add 6x to both sides
-6x + 6x - 3y = 9 + 6x
-3y = 9 + 6x             Or more conventionally
-3y = 6x + 9             Divide by - 3
y = 6x/-3 + 9/-3
y = - 2x - 3  
 
        
             
        
        
        
Answer:
Step-by-step explanation:
you have to use trigonometric functions
cos 30 = adj. /hyp.
cos 30 = 12 / y 
y = 12/cos 30 ≅13.86
tan 30 = opp./adj
tan30 = x / 12 
x = 12 tan30 ≅6.93
