Answer:

k = $\frac{91}{3}$

Step-by-step explanation:

Expand.

11k - 8 = 11 + 8k + 72

Simplify 11 + 8k + 72 to 8k + 83.

11k - 8 = 8k + 83

Add 8 to both sides.

11k + 8k + 83 + 8

Simplify 8k + 83 + 8 to 8k + 91.

11k = 8k + 91

Subtract 8k from both sides.

11k - 8k = 91

Simplify 11k - 8k to 3k.

3k = 91

Divide both sides by 3.

k = $\frac{91}{3}$

Tju [1.3M]

Answer:

$A = \sqrt{89}$

$B = \sqrt{145}$

Step-by-step explanation:

$1)\ 8^2 + 5^2 = A^2$

$2)\ A^2 = 64 + 25$

$3)\ A^2 = 89$

$4)\ A = \sqrt{89}$

$1)\ B^2 + 12^2 = 17^2$

$2)\ B^2 + 144 = 289$

$3)\ B^2 = 145$

$B = \sqrt{145}$
