Just so you know, you have to know at least one of the variables to find out what the other is. Like for example, X could equal 2, so that would make y equal 5. Or X could equal 23, and that would make y equal 26.
Answer:
If the base of the prism has dimensions x and y, and the diagonal along the base is represented by c, then x² + y² = c². The longest diagonal in the solid, s, is the hypotenuse of the triangle formed by the sides c and the height of the solid, z. So we know that, c² + z² = s².

The answer is 2(2x-3)
Explanation: First you multiple 5 and 2 getting you ten
4x-10+4
Then you add -10 and 4 to get -6
4x-6
Finally you factor out the number to and divide both the 4 and -6
2(2x-3)
9.52 per hour for 6 hours 2 days. there is a total of 12 hours in total so divide 114.24 by 12 to get 9.52.
