Answer 2

To solve this expression, you need to perform the matrix multiplication and then evaluate the absolute values. Given the matrices:

A = |12 8| |-6 25|

B = |-6 25| | -45|

Let's first calculate the matrix multiplication A * B:

A * B = |(12 * -6) + (8 * -45) (12 * 25) + (8 * -45)| |(-6 * -6) + (25 * -45) (-6 * 25) + (25 * -45)|

Simplifying the multiplications:

A * B = |-72 - 360 300 - 360| |36 - 1125 -1500 - 1125|

A * B = |-432 -60| |-1089 -2625|

Now, let's evaluate the absolute values for each element in the resulting matrix:

|A * B| = |432 60| |1089 2625|

So, the final result is:

|12, 8| * |-6, 25| + |-45| = |432 60| |1089 2625|
