- square root of 10 is between 3.1 and 3.2
- square root of 10 is less than 3.5
Step-by-step explanation:
√5 and √10 are plotted on the number line shown below.
Rounded to 1 decimal place, √5 ≈ 2.2 and √10 ≈ 3.2, so it could be said they differ by about 1 unit. The above answer choices are the ones that match the graph.

If we factor out the common x, we have:
x(-q - p), which can be rewritten as:
x(-q + -p), which is the sum of -q and -p,
