I need help on 23 !!

Step-by-step explanation:

1/4 * 2/3 = 2 / 12 = 1/6

3 different triangular borders.

Step-by-step explanation:

We have been given that Poong 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.

We will use triangle inequality theorem to solve our given problem.

Triangle inequality theorem states that sum of two sides of a triangle must be greater than measure of 3rd side.

Using triangle inequality theorem, we will get following possible borders:

1) 8, 10, 12.

2) 10, 12, 18.

3) 12, 18, 8

The border 8, 10, 18 will not work as .

Therefore, there are Ha Poong can make 3 different triangular borders.
