Help plzz I think it is 1 or 2 By The square root property, if k is a real number and x^2=k, then what is x equal to? 1. √k 2. =| √k 3. -√k 4. k^2

Step-by-step explanation:

k is a real number.

We take the square root of both sides of the equation.

Simplifying the equation.

x = ±√k

Step-by-step explanation:

If:

We'll take square root on both sides

=>

=> x = ±√k

The correct answer is D. 8/11 of an hour.

If she drove to the store twice, with each time consisting of exactly 3/4 of an hour, then that is equal to 6/8 of an hour. Then we add her one trip dropping her sons off at school, so we add 2/3 of an hour to our 6/8 of an hour. We receive a final answer of 8/11 of an hour.
