Solve for m.
3-2(9+ 2m) = m
m
what does m equal?

m=-3

Step-by-step explanation:

first multiply every thing out

3-18-4m=m

simplify

-15-4m=m

get all m's on one side

-15=5m

divide both sides by 5 to isolate m

-3=m

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
