C) First row = 0
D) First Column = 0

Help please!

A

Step-by-step explanation:

Null means nothing, or zero.

In the case of matrix, a null matrix is a matrix where all its elements are zeros.

They can be of any order, 2 x 3 matrix, 2 x 4 matrix, 2 x 2 matrix etc.

A matrix has a diagonal and other values (non-diagonal). When diagonal is 0 only, and not other, its is still not null. When all the values of a matrix are 0, all the elements are 0, then we call that Null Matrix.

It is equivalent to Zero (0) in the number system.

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
