Answer:
B. 1/9
Step-by-step explanation:
The positive square root of "x^2 - 4x + 4" is "x - 2". That value is already given to you, 1/3. Just square 1/3 to get 1/9.
B 1/9
x − 2 = 1/3
Add 2 to both sides
X+2-2 = 1/3+2
x = 7/3
Put x = 7/2 into the expression x² − 4x + 4
(7/3)² - 4(7/3) + 4
49/9 - 28/3 + 4
= (49-84+36)/ 9
= 1/9
