8(2z-6)
Distributive property

16z-48

Step-by-step explanation:

8(2z-6)

8*2z-8*6

16z-48

16z - 48

Step-by-step explanation:

8(2z-6)

To do the Distributive Property, multiply the number outside of the parenthesis by each number inside the parenthesis, to get something like this:

8(2z) and 8(-6)

16z - 48

((If you get a positive number for the second number then it'd be 16z + 48 but since it's negative it's 16z - 48))

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
