Someone please help me! I'm very confused. The help is very much appreciated!

Step-by-step explanation:

In similar figures, the corresponding sides will always be proportional to each other.

We know that quadrilateral HIJK is similar to LMNO. This means that:

By substitution:

Solve for NO. Cross-multiply:

Therefore:

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!
