The answer is c. Because you subtract 5 from 15 because you are dividing (if you were multiplying you would addition)
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 < ∞
It would be 12 ones it would be this because you have to add 7+ 5
