Draw a number line and mark on it, if possible, all described points. positive numbers

Step-by-step explanation:

Sorry tried my best

                                                                               All the positive numbers

                                                                          >

   -10   -9   -8   -7   -6   -5   =4   -3   -2   -1   0   1   2   3   4   5   6   7   8   9   10

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!
