The only one you might use it the triangle
 
        
                    
             
        
        
        
Dy/dx = -y inx iny
(y in x in y) dx + dy = 0
(y in x in y ) dx = - dy
(in x )dx =  - (1/ y in y) dy
you just need to integrate both sides
Hope this helps

Answer:
Not a factor
Step-by-step explanation:
We can use Factor Theorem to answer this question. According to this theorem, in order to find if (x - a) is a factor of a polynomial f(x), calculate f(a). If f(a) comes out to be equal to zero, this will mean that (x-a) is  factor of f(x).
Here, the expression we have is (x + 7), so we need to find f(-7) in order to check if (x+7) is a factor of f(x) or not

Substituting x = -7, we get:

Since f(-7) ≠ 0, (x + 7) is not a factor of the polynomial f(x)
