Solve the inequality , find the max possible value for the variable.
3t + 1 < t + 12
2t < 11
t < 5.5
t_max = 5.5
For the second question just solve as two separate inequalities
4 +2 < x <= 7 + 2
6 <x <= 9
x in ]6, 9]
This is a right triangle and you can use the Pythagorean theorem to find the missing side.
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
square root of 169 = c
13.
So the missing side is 13m
