An invasive species is a species that is not native to a given ecosystem. These species have a negative impact on the new environment. 
- It is well known that invasive species NEGATIVELY impact native species by establishing new ecological interrelationships (e.g., predation and competition).
- Moreover, invasive species may also cause great economic harm to the affected regions where these species are established.
- Human activity is the main cause associated with the introduction of invasive species into new geographical regions.
- In consequence, the statement that is NOT true about the impact of an invasive species on an ecosystem is it can stabilize the populations of native species.

or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
