Despite popular belief, investigators have gotten a tip that the loch ness monster is actually being kept as a pet in a scottish hotel (rooms numbered -10 to 10). four specially-trained monster hunters checked different rooms. none of them found nessie. through process of elimination, figure out where the nessie must be hiding. 1) x + 4 < 3 2) x 5 > 1 3) 2x + 3 > 11 4) -3x > -9 which room must nessie by hiding in?

room 3 or 4

We assume the inequalities tell the rooms that were checked and found empty.

The solution to 3) is ...

... 2x + 3 > 11

... 2x > 8 . . . . . subtract 3

... x > 4 . . . . . . .divide by 2

The solution to 4) is ...

... -3x > -9

... x < 3 . . . . . . divide by -3

Thus, rooms greater than 4 and less than 3 were found empty. Rooms 3 and 4 were not checked, so either one could hold Nessie.

The other inequalities have solutions that are already covered by the solutions to these.

1) x < -1 . . . . after subtacting 4

2) x > 5 . . . . after multiplying by 5

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
