Answer:

Step-by-step explanation:

MrRoyal

The possible lengths of the shortest straw are 5 inches, 6 inches, 7 inches and 8 inches

How to determine the possible lengths of the straw

The lengths of the two straws are given as: 9 inches and 12 inches

Represent the length of the shortest straw with x.

So, we have the following inequality

[tex]x + 9 > 12[/tex]

Subtract 9 from both sides

[tex]x > 3[/tex]

This means the length of the shortest straw is greater than 3 inches

Hence, the possible lengths are 5 inches, 6 inches, 7 inches and 8 inches
