Answer:
k = ± 3
Step-by-step explanation:
Isolate the absolute value by dividing both sides by 3
| 3k | = 9
The value inside the bars can be positive or negative, thus
3k = ± 3 ( divide both sides by 3 )

Yes because 5^2 + 12^2 = 13^2
We can check using the Pythagorean theorem
a^2 + b^2 = c^2
5^2 + 12^2 = 13^2
25+ 144= 169
169 = 169
