First you have to solve both inequalities,

3x-1>8

3x>9

x>3

and the other one

Aloiza [94]

Answer:

\sqrt{697}

Step-by-step explanation:

If the base of the square pyramid has an area of 576 units, then the side length must have a length of \sqrt{576}=24. 24/2=12, and using the pythagorean theorem you can find that the height of the pyramid is \sqrt{29^2-12^2}=\sqrt{697}. Hope this helps!
