Answer:

Step-by-step explanation:

To find the value of x, using Pythagorean theorem.

7) x² = 12² + 12²

        = 144 + 144

       = 288

x     = √2*12*12

x = 12√2

8) x² + 9² = 18²

x² + 81 = 324

x² = 324 - 81

x² = 243

x = √3*9*9

x = 9√3

Find the determinancof the matrix Q.
stepan [7]

Using a Laplace expansion along the first column, we have

\det Q=2\det\begin{bmatrix}2&1\\-1&6\end{bmatrix}+3\det\begin{bmatrix}3&4\\-1&6\end{bmatrix}+5\det\begin{bmatrix}3&4\\2&1\end{bmatrix}

The determinant of a 2x2 matrix is trivial,

\det\begin{bmatrix}a&b\\c&d\end{bmatrix}=ad-bc

So we have

\det Q=2\cdot13+3\cdot22+5\cdot(-5)=67
