Put these numbers in order from least to greatest: √175, −7π, 7, −19.38.

To order the numbers from least to greatest, we need to evaluate each one:

1. √175: This is approximately 13.23 (since √169 = 13 and √196 = 14).
2. −7π: Since π is about 3.14, −7π is approximately −21.98.
3. 7: This is simply 7.
4. −19.38: This is a negative number, which is less than -19.

Now we can compare the approximate values:

– −21.98 (−7π)

– −19.38

– 7

– 13.23 (√175)

Putting them in order from least to greatest:

−7π, −19.38, 7, √175.

So, the final order is:

−7π, −19.38, 7, √175.
