It's scalene because it has different sides and obtuse because root 40²+30²=50
110>50
It would be
(X^4+2X^2) -119(X^2-2X) then you would simplify
X^4+2X^2-119X^2-2X
So it would be
X^4+117X^2-2X=0
So basically X is undefined
The answer to that is 7 but i dont get the last part
Y = - x^2 - 2
the vertex of - x^2 will be at (0,0)
the -2 translates the graph down 2 units
The answer is the vertex is at (0,-2) and as the coefficient of x^2 is negative it is a maximum
Answer is D.
Answer:m is the gradient or slope
B is the intercept
