Question

Please help! Correct answer only, please! I need to finish this assignment this week. Find the product AB, if possible. Explain if it is not possible. A. B. C. D.

Answer 1

C

Explanation:

The matrices are conformable for multiplication.

Multiply and sum the product of corresponding elements in row 1 of matrix A with elements in column of matrix B.

AB =
`\left[\begin{array}{ccc}5(2)+2(3)\\3(2)-1(3)\\\end{array}\right]` =
`\left[\begin{array}{ccc}10+6\\6-3\\\end{array}\right]` =
`\left[\begin{array}{ccc}16\\3\\\end{array}\right]` → C
