For the midpoint, you find the differences in x values and y values then divide them by 2. Like so:
Let's do x first:
(-16-0)/2 = (-16)/2 = -8
So our x coordinate is -8.
Now Y:
(-16)/2 = -8
So our Y coordinate is -8 as well.
So your answer is:
(-8,-8)

-2 < n

3
This inequality basically says "-2 is less than n, which is less than or equal to 3".
Mark as brainliest if this helped! :)
X^3 + 7*x^2 + -16*x-112
=(x + 4)*(x + 7)*(x - 4)
