You have baked 48 cookies. you want to keep 12 for your family, the rest you want to split between 9 friends. how many cookies will each friend receive?

4 cookies each

Step-by-step explanation:

48 - 12 = 36 cookies for friends

36/9 = 4 cookies for each friend

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!
