Answer:
Four unique planes
Step-by-step explanation:
Given that the points are non co-planar, triangular planes can be formed by the joining of three points
The points will therefore appear to be at the corners of a triangular pyramid or tetrahedron such that together the four points will form a three dimensional figure bounded by triangular planes
The number of triangular planes that can therefore be formed is given by the combination of four objects taking three at a time as follows;
₄C₃ = 4!/(3!×(4-3)! = 4
Which gives four possible unique planes.
F14.33 1425,413 that’s the right number
45 because 180 divided by 2=90 and 90 divided by 2= 45 because she needs area which is length times width= area and area divided by length or width= the other
Answer:
x <= - 4 2/3
Step-by-step explanation:
3(x-4) ≥ 6x+2
Distributive property
3x - 12 ≥ 6x+2
-12 ≥ 3x + 2
re-write
3x + 2 <= -12
3x <= -14
x <= -14/3
x <= - 4 2/3
