The answer would be 15,120
Answer:
8
Step-by-step explanation:
+2-(-6)=2+6
the two negatives cancel each other out
2+6=8
If you meant -3x then the answer is (2,12)
Check the picture below.
first off we'll need to know the midpoints of ST and UV, well, from ST as you can see in the picture, is just a vertical line, so its midpoint is simply (-2,0), let's find it for UV
