Answer:

Step-by-step explanation:
We can find the inverse function of this excercise, isolating X and then changing the variables.


And now we change the variables and we get the inverse function:

This looks like scalar matrix multiplication. The idea here is to multiply the scalar 3 by each item inside the matrix.
Doing so leads to the answer [3 -12 15 -21]
Side note: I'm assuming the matrix given to you has 1 row and 4 columns.
Answer:
Options A and Option B
Step-by-step explanation:
All four sides AX, IX, IS and AS of the base are common in the four side walls of the prism.
In other words, edge AX is common in planes AXU and AXS,
Edge XI is common in planes XIB and AXS,
Edge SI is common in planes EBS and AXS,
Edge AS is common in planes CEA and AXS.
Therefore, plane AXS is intersecting planes AXU and EBS.
Options A and Option B are the correct options.
