440 is your answer
The answer to the equation is x=30
The answer is option C) 19,-19
<u>Step-by-step explanation</u>:
Given, z² = 361
To eliminate the square of z, take square root on both sides
z = √361
- The factor of 361 could not be an even number, since the last digit of 361 is odd. So, eliminate option A)
- The option B) is a larger number and it cannot be the answer. So, eliminate it.
- Try option C) works or not. (19)² = 19
19 = 361 and (-19)² = -19
-19 = 361. - Therefore, z = √361 = ±19. option C) is the correct answer.
Your answer is negative threee
