Answer 1

Answer:
`√(18) \approx 4.2`, see attached for graph

Explanation:

The perfect square roots surrounding
`√(18x)` are
`√(16) =4` and
`√(25) =5`. This is why the number line given is between 4 and 5.

4.3 * 4.3 = 18.49, so that is too big.

4.1 * 4.1 = 16.81, so that is too small.

`√(18) \approx 4.2`
