Answer:
What is your question? A plane does need three points so this would make sense.
Step-by-step explanation:
A plane must have three points, otherwise it could be a line (from two points) or a single point (one point).
Answer:
n=-19
Step-by-step explanation:
-9+n/4=-7
Multiply 4 on both sides
-9+n=-28
Add 9 on both sides
n=-19
83x + P = 83x + Q <em>subtract 83x from both sides</em>
P = Q
The equation has no solution for P different Q (P ≠ Q).
