Question

Use the distributive property to factor the expression.
2k + 10

I don't know how to solve this question, please help. :(

Answer 1

To factor two terms, you must see what values they share. In this case both 2k and 10 have 2 as a factor. So to factor do this 2(k+5). Notice how this is the same as the expression above just not distributed out

Answer 2

Hello, I need help on prime numbers. My teacher says that 3,5, and 7 are prime while my partner thinks it's 6,10 and 12. I need a tutor to give me proof that it is 3,5, and 7.

Answer 3

Prime numbers are numbers which factors are 1 and itself. For example the factors of 3 are 1,3. For 5 they are 1,5. For 7 they are 1,7. The other three numbers given are composite numbers which have more than 2 factors. ex) 6= 1,2,3,6 10=1,2,5,10 12=1,2,3,4,6,12
