Is it possible to contruct a 4x3 matrix b and a 3x4 matrix c such that bc is invertible?

Lady bird [3.3K]

Matrix B has dimensions 4x3
Matrix C has dimensions 3x4

Write out those dimensions like so: 4x3 3x4
The inner '3's match up so B*C is possible. The dimensions of B*C is 4x4 as these are the outer dimensions when lining up 4x3 3x4

Since B*C is a square matrix, it is possible that an inverse could exist. Keep in mind that this isn't a guarantee as the determinant of B*C could be zero (which would lead to BC being non-invertible). Though of course we'd need more info.

How many liters of water can the three containers hold in all? Container 1: (x-1) Container 2: x Container 3: (x+1)

MariettaO [177]

We know that:

Container 1: can hold $(x-1)$
Container 2: can hold $(x)$
Container 3: can hold $(x+1)$

In total there are $3x's$

$-1+1 = 0 
$

Therefore, the correct answer is 3x.
