If you add up the two smaller sides, you should get a number greater than the longest side. Then you know it is a triangle.
For example: 3, 4, 5.
3 + 4 = 12.
12 > 5; so three, four and five make up a right triangle.
2, 3, 5
2 + 3 = 5
5 is not greater than five, so that would be not be a triangle.

The teacher will need 10 packages of markers. If 8 markers to a package, 10 packages= 80 markers. If 25 students shall have 3 markers each, that comes to equal 75. So the teacher needs 10 packages and will have five left over.
Answer is b
4000/12 = 333
333+80 = 413
413*20= 8260 they have enough
400/12=333
333*22= 7326 not enough
