Answer:
Linear Pair and then Vertical i belive.
Step-by-step explanation:
Expand
f(x)=-x²-8x-12
take derivitive
f'(x)=-2x-8
zero at x=-4
in x<-4, the derivitive is positive so the function is increasing
in x>-4, the derivitive is negative so the function is decreasing
increasing in (-infinity,-4)
decreasing in (-4,infinity)
first option
The estimation for 279 would be 280
4 times three of anything is 12 of the same thing. It doesn't matter
whether the things are cows, books, children, or sevenths.
