A
x = 11
B. x=21
C. X = 61
D. x=-11
E. X=-21
Answer:
x = 11, x = -11
Step-by-step explanation:
I know this is kind of late but the two previous answers were wrong.
We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:
√x² = √121
x = √121
You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.

Step-by-step explanation:
Step 2: x = 24 − 8
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Tina's solution?
She did not divide 24 by 8.
She did not add 8 to 24.
She did not multiply 24 by 8.
She did not multiply 24 eight times.
Answer: The correct statement is (A) She did not divide 24 by 8.
Step-by-step explanation: Given that Tina solved an equation incorrectly, as shown below:
Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16.
We are to select the correct statement that best explains the reason behind Step 2 incorrect.
The correct steps of the solution are
Therefore, we see that in step 2, Tina should divide 24 by 8, which she did not do and got the incorrect answer.
Thus, the correct statement is (A). She did not divide 24 by 8.
