Larry Buckley · Answer 1

A number line that shows all the positive numbers, and in this case it is 8. The number would be to the right. Positive 8.

Tania Bailey · Answer 2

There should be a dot at 8 and at - 8

Step-by-step explanation:

x^2 = 64

Take the square root of each side

sqrt (x^2) = sqrt (64)

x = ±8

There should be a dot at 8 and at - 8
