Answer:
I think its D? I'm not sure sorry if I get it wrong
Answer:
(-3, -7)
Step-by-step explanation:
Let 
The midpoint coordinates
of any two points
and
are given by
and 
Since B is the midpoint of AC


Since E is the midpoint of B and D and we are given the coordinates of E as (-4,-3). it follows that

Therefore

Similarly

The answer is 20 because you would do (5-9) which is -4 multiplied by -5 is positive 20
