Answer:

Step-by-step explanation:

3|2x-2| = 18-6

|2x-2| = 12/3

|2x-2|=4

2x-2 =+-4

2x -2 = -4

2x= -4+2

2x=-2

x=-1

2x -2 = 4

2x= 4+2

2x=6

x=3

Evaluate the determinant for the following matrix: 1 4 4 5 2 2 1 5 5

Elina [12.6K]

A Laplace expansion along the first row gives

$\begin{vmatrix}1&4&4\\5&2&1\\1&5&5\end{vmatrix}=1\begin{vmatrix}2&1\\5&5\end{vmatrix}-4\begin{vmatrix}5&1\\1&5\end{vmatrix}+4\begin{vmatrix}5&2\\1&5\end{vmatrix}$
$=1(10-5)-4(25-1)+4(25-2)$
$=1$
