Answer:

x = 8
BF = 45

Step-by-step explanation:

Using the given information, we have ...

BH = 2·HF

3x +6 = 2(2x -1)

3x +6 = 4x -2

8 = x

The length of the median is ...

BF = BH + HF

BF = (3x +6) +(2x -1) = 5x +5

BF = 5·8 +5

BF = 45

Can you think of any 2x2 matrices d for which cd = dc for all 2x2 matrices c? give 2 different examples of such matricesd.

Ksju [112]

For any arbitrary 2x2 matrices $\mathbf C$ and $\mathbf D$ , only one choice of $\mathbf D$ exists to satisfy $\mathbf{CD}=\mathbf{DC}$ , which is the identity matrix.

There is no other matrix that would work unless we place some more restrictions on $\mathbf C$ . One such restriction would be to ensure that $\mathbf C$ is not singular, or its determinant is non-zero. Then this matrix has an inverse, and taking $\mathbf D=\mathbf C^{-1}$ we'd get equality.
