Step-by-step explanation:
Rank of a matrix is the dimension of the column space. Rank Theorem : If a matrix "A" has "n" columns, then dim Col A + dim Nul A = n and Rank ... There are no pivots in columns 3 and 5.

Answer:
Rank(A) + dim Nul(A) = the number of columns of A (n)
Step-by-step explanation:
If A is any m × n matrix, then
The dimension of its column space or row space is called the rank of A
The dimension of its null space is called as nullity of A
The connection between these two dimensions is given by the rank nullity theorem that is,
Rank(A) + dim Nul(A) = the number of columns of A (n)
Therefore Rank(A) + dim Nul(A) = the number of columns of A
