| x-3 -8 -16 | = 0, determine the value of x.
| 3 9 4 |

Answer 1

Answer:

¶^∆€€[©17#93]π√℅h543

Answer 2

Answer:

98

Step-by-step explanation:

In the given determinant,

We are given the following determinant.

To calculate the value of x we need to open up the following determinant and write down the terms and after that the value of x can be found out easily.

$\left[\begin{array}{ccc}5&4&8\\(x-3)&-8&-16\\3&9&4\end{array}\right]=0\\ 5(-32+144)-4[4(x-3)+48]+8[9(x-3)+24]=0\\560-16x-144+72x-24=0\\392-40x=0\\x=98$

On opening the determinant we get the value of x = 98.

Therefore, the value of x is equal to 98.

The value of x = 98.
