I wasn't taught this specifically, but I would think that it would mean two ratios are involved with the same problem, just like it says.
Answer:
i. hexagon
ii. triangle
iii. octagon
iv. square
v. pentagon
vi. rectangle
Step-by-step explanation:
A two-dimensional figure is a flat figure that is described by its length of sides only. It can be obtained from a three dimensional solid when sliced or truncated.
Truncation is the process of cutting a solid with respect to a given plain. Therefore, when a three dimensional solid is truncated, the face forms a two dimensional figure. An example is when a cube is truncated horizontally, a square can be obtained at the surface.
Answer:
The formula is not valid because the commutative property with respect to the matrix product operation is not fulfilled in the vector space of the real matrices.
Step-by-step explanation:
The formula is not valid because the commutative property with respect to the matrix product operation is not fulfilled in the vector space of the real matrices. That is, AB does not necessarily equal BA.
