I think its the second one. I hope it is
To answer the question above, raise both sides of the equation to the power of two.
(sqrt (2x + 1))² = 3²
This will simplify into,
2x + 1 = 9
Solving for the value of x gives an answer of x = 4. This value is not an extraneous root as it satisfy the original equation even if it is inside the radical sign. (I hope this is right)
Answer:
yes
Step-by-step explanation:
Option D:
The solution to the equation is y = 27.
Solution:
Given equation:

To solve this equation:

Multiply by 3 on both sides of the equation.

3 in the numerator and denominator get canceled.
y = 9 × 3
y = 27
The solution to the equation is y = 27.
Option D is the correct answer.
