Hello.
The answer is 130.
130 is the only number so that has to be the mean.
This is beacsue <span> symmetric is the same as the mean.
Have a nice day</span>
By the PEMDAS rule, as long as the stuff inside the parentheses add up to 42, it would be correct. Therefore:
A. Correct because 40 + 2 = 42
B. Correct because 20 + 22 = 42
C. Incorrect because 4 + 20 = 24 ≠ 42
D. Incorrect, because 4 + 2 = 6 ≠ 42

Answer: 25x^10
Step-by-step explanation: First apply the exponent rule. (5x^5)^2 = 5^2(x^5)^2
5^2 = 25 = 25(x^5)^2. Now take (x^5)^2 and simplify it. Use the exponent rule for (x^5)^2 = x^5 * ^ 2. Multiply 5 * 2 = 10. So, it becomes x^10. So, take the 25 and plug in the 10. 25x^10 is the answer.
