A) AB is where plane P and plane R intersect.
B) A, D, B are collinear (on the same line).
C) plane ADG (three points on the plane)
D) F, D, G, A are all on plane R
E) D lies on both planes.
Answer:
B
Step-by-step explanation:
yes, 12² + 13² = (
)²
144 + 169 = 313
313 = 313
12j + 12 + 3j or 15j + 12. This is because if you use Distributive Property to distribute the 3, then you multiply 3 by all the number inside the parentheses. I have two expressions because once you get get the answer after you use the property, then you can combine like terms, such as 12j and 3j which is 15j. Hope this helps!
M is a midpoint of BC so:
