Which statements about square roots are true? Check all that apply.
The square root of a positive number cannot be negative.
All positive numbers have two square roots.
18 = 9 because 9(2) = 18.
149 = 7 because 7(7) = 49.
25 = 5 because 52= 25.

The only correct answer is:

All positive numbers have two square roots

Step-by-step explanation:

This is true because in any situation all positive numbers have two square roots. For example, the square root of 25 is +/- 5 which means that 5 is a square root (because 5x5=25) and -5 is a square root (because -5x-5=25).

The others such as 18 = 9, 149 = 7, and 25 = 5 are all false statements.
