Answer:
AB =-4 24 25
-5 15 15
BC= -5
4
10
2BC = -10
8
20
THE Operation AB -2BC cannot be performed because the unequality of the arrays
Step-by-step explanation:
AB=first row (3*2)+(1/2*0)+(5*-2), (3*-4)+(1/2*2)+(5*7), (3*0),(1/2*0),(5*5)
Second row ((1*1)+(-1*0)+(3*-2),(1*-4)+(-1*2)+(3*7), (1*0)+(-1*0)+(3*5)
AB =-4 24 25
-5 15 15
BC =FIRST ROW (1*1)+(-4*2)+(0*0)
SECOND ROW (0*1)+(2*2)+(0*0)
THIRSD ROW (-2*2)+(7*2)+(5*0)
BC= -5
