Given: 2<span>√(x - 5) = 2
Taking the square of both sides:
[</span>2√(x - 5) = 2]^2
4(x - 5) = 4
x - 5 = 1
x = 6
Among the choices, the correct answer is A. <span>x = 6, solution is not extraneous .</span>

Answer:
She runs for 1.6 hours
Step-by-step explanation:
For this, one way to do it is to just set 1 hour over 4 miles equal to x hours for 6.4 miles. The reason this is done is because if the speed is constant that means the rate stays the same, which means the ratio of miles to hours should always be the same, so the two ratios must be equivalent.
1/4 = x/6.4
Multiply both sides by 6.4 to get x by itself:
6.4/4 = x
1.6 = x
Hope that helps!
