Question

Which number line represents all of the values of x for the equation x2 = 25?

A number line is shown from negative 25 to 0 to positive 25. There are increments of 5 on the number line, and all these increments are labeled. A dot is shown on positive 5 and is labeled as p.

Answer 1

X2=5. Square root of 25 =+_5 The number line with the plot on positive 5 and negative 5

Answer 2

Answer with explanation:

The given equation is:

`x^2=25\\\\x^2=(\pm 5)^2\\\\ x=\pm 5`

On the number line, mark circles on 5 and -5 , respectively.

Option B:

A number line is shown from negative 25 to 0 to positive 25. There are increments of 5 on the number line, and all these increments are labeled. A dot is shown on positive 5, another dot is shown on negative 5 and they are labeled as p and q, respectively.
