Which figure cannot be created from a plane section of a cube? A triangle

B Square

C octagon

D trapezoid

C). Octagon.

Step-by-step explanation:

A cube has 6 plane faces. That would mean any plane slice that can intersect at most 6 of those faces, creating a hexagon. Not a single plane figure with more than 6 sides could be created by slicing a cube with a plane.

Therefore the answer is C, octagon.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
