Add them all up and if they add up to 180 then your side lengths are good
        
             
        
        
        
Answer:
y = -  x²
 x²
Step-by-step explanation:
Since the vertex is at the origin and the focus at (0, - 4) then the parabola opens vertically down with equation
x² = 4py ( p is the distance from the vertex to the focus )
Here p = - 4 ( focus is below the vertex ), thus
x² = 4(- 4)y = - 16y ( divide both sides by - 16 )
y = -  x²
 x²
 
        
             
        
        
        
Answer:
Factoring is taking the greatest factor of an equation/expression and putting it behind parenthesis.
For example:
2+4: Factor it
2 is the greatest factor of the two
SO
2(1+2)
Ill give you a try it and you can factor it. I might check it later on.
42+ 36
If you are looking for something harder:
4x^4+ 6x^6
