Determine whether the following statement is true or false: Given matrices A of the size 4 x 4 and B of the size 4 x 4. If a matrix AB (if possible) is non- invertible (singular) then both matrices A and B must be also non-invertible (singular). Select one: O True O False Determine whether the following statement is true or false: If both matrices A of the size 2 x 5 and B of the size 2 x 5 have row echelon forms (REF) then a matrix AB (if possible) must have a row echelon form (REF). Select one: True False
