The correct answer is:
there must be at least two lines on any plane because a plane is defined by 3 non-collinear points.
Explanation:
Since a plane is defined by 3 non-collinear points, we could have: a line and a point not on that line; two intersecting lines; two parallel lines; or simply 3 non-collinear points.
For 3 non-collinear points: If none of the 3 points are collinear, then we could have 3 lines, 1 going through each point. These lines may or may not intersect. If two of the 3 points are collinear, then we have a line through those 2 points as well as a line through the 3rd point.. Again, these lines may intersect, or they may be parallel.

Answer:
The answer to question 3 is : 2x^2 + 5x + 3
Step-by-step explanation:
The FOIL method is multiplying the first variables, the outside variables, the inside variables and the last variables.
(2x + 3)(x + 1)
F = 2x times x = 2x^2
O = 2x times 1 = 2x
I = 3 times x = 3x
L = 3 times 1 = 3
2x^2 + 5x + 3
I'll leave the rest to you. You got this!
Hope this helps have a nice day
