Dr.king was born on January 15, 1929 and he died on April 4, 1968.

Yes.

Is there a question here?

Ms. Sue, sorry the question was to punctuate the following sentences correctly and write the formula you used: [s;s] or [s, conj s]

I don't know the formulae you are being taught. In a compound sentence such as this, a comma may be used before the conjunction "and", but is not necessary. The sentence is fine as is. (But Dr. King should be capitalized.)

A comma is used to set off a year. You need a comma after 1929.

That is correct. Dr. Martin Luther King Jr. was born on January 15, 1929, and he died on April 4, 1968. To verify this information, you can follow these steps:

1. Open a web browser.
2. Go to a reliable search engine's website, such as Google or Bing.
3. Type "Martin Luther King Jr. date of birth" in the search bar.
4. Press Enter or click on the search button.
5. Look for a trusted source, such as an official biography or a well-known historical website, to find the confirmed date of birth.
6. Repeat the process, but this time search for "Martin Luther King Jr. date of death."
7. Once again, find a reliable source to obtain the verified date of death.

By following these steps, you can confirm that Martin Luther King Jr. was indeed born on January 15, 1929, and he died on April 4, 1968.
