Ask for work, everyone help, please help,

In the middle school context, there is no solution to this problem, which is determined by the nature of odd and even numbers. Because the numbers given in this problem are all odd numbers, and the sum of three odd numbers is still an odd number, and it is impossible to get an even number of 30, so there is no solution to this problem.

However, when you get to university, you will have a solution to this problem, and the solution involves derivatives. Derivative is an important fundamental concept in calculus. When the independent variable x of the function y=f(x) produces an incremental δx at a point x0, the ratio of the incremental δy of the output value of the function to the incremental δx of the independent variable is at the limit a when δx approaches 0 if it exists, a is the derivative at x0 and is denoted as f'(x0) or df dx (x0).

The derivative of any constant is 0, and the sign of the derivative is ', so the three blanks are filled with 15, 15, 15'. 15'=0, i.e.: 15+15+15'=30

Note: 15'=0 The derivative of any constant is 0

If you write the question, you can only fill in (1,3....)15), including, of course, "().""with","These three symbols,"The question was given, but it was changed to a different position and put on it to become a derivative symbol" ' "Please adopt.

The numbers given are all odd numbers, and 3 odd numbers cannot be equal to even numbers, and if you want to answer 15+15, one is blank.

There is no answer to this question, the sum of 3 odd numbers is still odd, 30 is an even number, there is no answer.

Dear, please [adopt the answer], your adoption is the motivation for me to answer the question, thank you.

I'm still short of people, so contact me when you feel like you'd like to come and see it.

Solve the 8 yuan book as x books.

8x+(105-x)×12=1500-4188×+1260-12×=1182

Answer: No, the integer solution is definitely wrong.

If you really like it, just wait. Two years is not very long either. You have to try to make yourself good and let him come back and see a new you.

You'll only be 17 in two years, and you'll still have a long time in your life. I'm 17 years old. It's about to be a sophomore year of high school.,Although I don't like to read either, I've always worked hard.,I worked hard because of a boy.,Because I love him too much, I've done too many stupid things.,He's my ex-boyfriend,.

Although I played a few after breaking up with him, I didn't feel that way anymore, I kept waiting for him. It's been three years, and his girlfriend doesn't know how many times I've changed, and I'm still waiting. Oh, they said why did I have to hang myself on this tree, I said:

Because he is him, because I am me. At the beginning, I just wanted to be good and studied hard, but he didn't get into high school. ......Uh.........I found out that I was pulling away .........In short, I hope you will still work hard for the rest of the year, and it will be up to you to wait or not.

Comparatively love doesn't come easily.

I'm very fond of a girl who failed, oh, no one ever liked me. I forgot about my studies, and I wasted my spirit where I shouldn't, and I missed a good high school. I'm now one up.

Does he like you? I don't care about age or anything like that, I chase as long as I like it. If the other party does not respond for a long time, but even if he changes his mind one day, then I will already be disheartened with him.
