Answer:
-x^2-2x-3
Step-by-step explanation:
-  Question 1: Just substitute in the values of f(x) and g(x) and simplify!
- f(x) - g(x) = 4x^2-5x+3-(5x^2-3x+6)
- f(x)-g(x) = 4x^2-5x+3-5x^2+3x-6
- f(x)-g(x) = -x^2-2x-3
Tell me if this helps, and if you still need number 2 or if you can do it by yourself! (Hint: substituting also plays a role in question number 2.)
Hope this helps!!
 
        
             
        
        
        
Answer:
√194 i think
Step-by-step explanation:
 
        
                    
             
        
        
        
Line of symmetry is the line which cuts the figure into two same halves
or we can say that which passes through the figure such that it makes one half the mirror image of the other half
So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves
So 
y=-2

The next larger thousandth is 36.994 .
The next smaller thousandth is  36.992 .
Neither of those is any nearer to  36.993
than  36.993  already is.
The last '3' at the end of 36.993 is in the thousandths' place.
There is no more piece of another thousandth after it.
So  36.993 is already on a complete thousandth, and
there's no rounding required.
