Answer:
The distance formula is 
The midpoint formula is 
Step-by-step explanation:
apply the pythagorean theorem on a coordinate grid
Answer:
Two negative make a positive so this equation is basically 39 = n + 12 so you need to subtract 12 from each side. This makes it n = 27

Answer: C: The orientation of the figure stayed the same
Step-by-step explanation:
Everything else is true
A. The figures do not change in dilation so they are still congruent
B. The pre-image does start in the top left which is quadrant 1
C. The orientation changes because the picture is reflected instead of translated so points D and E are in different respective locations
D. The image is a reflection. You can tell because both points D and E reflect across the Y-axis
7(2+5v)=3v+14
14+35v=3v+14
-3v -3v
14+32v=14
-14 -14
32v=0
÷32 ÷32
v=0
