## anonymous one year ago Use the expression 4w + x – 11y + 14z – 18 to answer the questions below. a. How many terms are in the expression? List the terms. b. What is the constant in the expression? c. What is the coefficient of the term 14z? d. What is the coefficient of the term x? Please help and explain.

the constant is just the number eg: 2x+1 : 1 is the constant

3. anonymous

coefficient of the term 14z: it is the number before the letter example: 6c the coefficient is 6

The constant is just a number. It has no letter beside it. Please refer to my previous reply for an example.

6. anonymous

So the constant would be 18?

7. anonymous

-18. Don't forget the sign.

8. anonymous

Oh, okay! So the coefficients are 4, 11, 14..? (:

4w + x – 11y + 14z – 18 "the coefficients are 4, 11, 14." The coefficient of 4w is 4. Yes! The coefficient of -11y is not 11. The coefficient of 14z is 14. Yes! What is the coefficient of x?

10. anonymous

Mmm.. either none or -18.

11. anonymous

None?

12. anonymous

No. It's not none. If I have \(\huge y\). It means \(\huge 1y\). So the coefficient is 1.

13. anonymous

14. anonymous

If it's none, then it shouldn't be in the expression because it is 0.

15. anonymous

Also, so if it is a negitive number it doesnt count as a coefficient?

16. anonymous

It could be a coefficient. That 's why I said, "the coefficient of -11y is not 11" because you forgot to put the sign.

17. anonymous

Oh, okay. So a term is a number or letter?

18. anonymous

Yes. A term could be \(\huge6z, 9, -11xy, 99s^2,... \)

19. anonymous

Thank you so much.

Sure no problem! :)

Of course! :)

Would you mind if I put up words to match? I dont have my math book yet. @mathway

25. anonymous

What do you mean?

26. anonymous

There are words that I have to match with deffintions. Can you help?
