Answer 1

To find the total length of the tree and its roots, we need to add the height of the tree above ground (3 feet) and the length of the roots underground (1 foot).

The total length can be represented by the equation:

\[ 3 + 1 \]

However, let's analyze the response choices given in the context of absolute values:

1. \(|3| + |1|\): This represents 3 + 1, which is correct.
2. \(|3| + |−1|\): This represents 3 + 1, which is also correct since \(|−1| = 1\).
3. \(|3| - |1|\): This represents 3 - 1, which is not correct.
4. \(|−1| - |3|\): This represents 1 - 3, which is negative and not correct.

The correct responses that represent the total length of the tree and roots are:

• \(|3| + |1|\)
• \(|3| + |−1|\)

Either of those can be used to express the total length as they yield the same result of 4.
