Answer:
see below
Step-by-step explanation:
f(x) = –(x + 6)(x + 2)
The function is increasing until it reaches the vertex, so it will increase until x=-4. The function will decrease after the vertex, so after x = -4
increasing: -∞ < x < -4
decreasing : -4 < x < ∞

Answer:
6
Step-by-step explanation:
I'm going to assume that this is a right triangle
which means that

9x²+36=361
9x²=325
3x=18.0277
x=6
