Answer:
(-3,-12)
Step-by-step explanation:
Multiply the first equation by three to match the second equations y-term
The y-terms cancel out
Add the x-terms with each other and the terms after the equal sign as well
Divide -57 by 19
Input your x-term (-3) into one of the two first equations and multiply
Either:
Simplify your terms
Divide 
 
        
             
        
        
        
The money is a lot so it would be c
        
             
        
        
        
Yes. A triangle with three sides given can be cut out.
        
             
        
        
        
In isosceles right triangle, legs are equal. Let each leg is of x units . And the given hypotenuse is 5 square 6. We use pythagorean identity here, which is

Where a=b=x and c= 5 square root 6




And that's the length of both the legs . ANd that's the required answer .
 
        
             
        
        
        
Due to the distance formula the answer should be root 113 or 10.63
