Ennis can make two triangular borders from the given sticks.
Given information:
Ennis has 4 lengths of wood from which he plans to make a border for a triangular-shaped herb garden.
The lengths of the wood borders are 8 inches, 10 inches, 12 inches, and 18 inches.
Now, a triangle has a property that the sum of two sides should always be greater than the third side.
So, by applying this rule, the pairs of sides should be,
8, 12, 18
10, 12, 18
Two triangular borders can be made from two pairs of sides.
8, 10, 18 can not form a triangle as 8+10=18.
Therefore, Ennis can make two triangular borders from the given sticks.
