Please help need this answer

Step-by-step explanation:

The next (best) step is to divide everything by a.

D is not correct because only bx is divided by a. You cannot neglect to divide -c by a

B will eventually be done in some form but it is much easier to deal with division by a. The way b is done is not correct.

A is completely wrong. It's far to soon to be dealing with square roots.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

it is not that hard all u have to do is plot the graph
