SOME ONE HELP PLSSSS

which number line represents all of the values of x for the equation x2=100?

(picture below)

Answer 1

The correct answer is option A.) “-10 and 10.”

To find the values equivalent to that of x^2 = 100, we need to identify the square root of 100. The only number that can be multiplied by itself to give us a product of 100 is 10, so 10 is the square root; however, a negative • a negative always equals a positive. This means where 10 • 10 = 100, -10 • -10 also equals 100.

Hence, option A is the answer.
