which shows the phase the product of a number and 3 as a variable expression

Directrix (directrix):

Product is the name of th answer in multiplication. >> the product of a number and 3 as a variable expression If x represents the mystery number, then multiple it by 3 to get ?

Directrix (directrix):

You may need to post the options.

Directrix (directrix):

If x is the variable and you multiply by 3, what is the result?

OpenStudy (anonymous):

n + 3 n - 3 3n + 3 3n

OpenStudy (anonymous):

those are the choices ^

Directrix (directrix):

Okay. n is the variable. Multiply 3 by n to get the answer. The answer is the product of 3 and n.

Directrix (directrix):

Nothing has been added or subtracted so you can eliminate those options. That leaves one remaining option. What is it?

OpenStudy (anonymous):

ok but what is n ?

Directrix (directrix):

We don't know what n is. It is called a variable because it varies and can be just about any number.

Directrix (directrix):

3 times 5 = 15 but 3 times n cannot be "simplified" in that way because we do not know the value of n.

Directrix (directrix):

If you had to choose an answer now, what would you choose? Be Brave.

OpenStudy (anonymous):

i would go with C i think

Directrix (directrix):

3n + 3 is not correct because the phrase said three times a number n. Nothing was said about adding 3.

Directrix (directrix):

The answer is the product of 3 and n. It is 3n which is the last option.

OpenStudy (anonymous):

ah ok

Directrix (directrix):

I know it seems that there should have been more to the problem but not this time. :)

Directrix (directrix):
