Answer:
![\left[\begin{array}{cc}6&18\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D6%2618%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
To find the product of the matrices:
× ![\left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-2%265%5C%5C7%26-1%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Multiply rows of the first matrix by the columns of the second matrix.
(4 × (–2) + 2 × 7 4 × 5 + 2 × (–1))
After simplifying this, we get the product ![\left[\begin{array}{cc}6&18\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D6%2618%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Hence,
×
= ![\left[\begin{array}{cc}6&18\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D6%2618%5C%5C%5Cend%7Barray%7D%5Cright%5D)
