Question

What is the value of the determinant? ​

Answer 1

The value of the determinant is 0.

Explanation:

Since it is a 3 x 3 determinant, we can calculate its value by the Law of Sarrus:

`Det = (11)\cdot (98)\cdot (26\cdot y) + (97)\cdot (24\cdot y) \cdot (13) + (22\cdot y) \cdot (12) \cdot (99) - (22\cdot y) \cdot (98) \cdot (13) - (97)\cdot (12) \cdot (26\cdot y) - (11) \cdot (24\cdot y) \cdot (99)`

`Det = 28028\cdot y + 30264\cdot y + 26136\cdot y - 28028\cdot y - 30264\cdot y - 26136\cdot y`

`Det = 0`

The value of the determinant is 0.
