Answer:

C. 3n+9>21

Step-by-step explanation:

Ignore the 9 for a second and think about the phrase "3 times a number", if we say n is the number, then 3n is 3 times the number n.

Now we need something that is 9 more than this 3n, that means you add 9 to this, so you have 3n+9.

Finally, this 3n+9 is greater than 21, so we have 3n+9>21.

Your question is a bit unclear, but I will try to answer it anyway.

The expression 3x + 2(x - 1) - 4 simplified is:

3x + 2(x - 1) - 4

= 3x + 2x - 2 - 4

= 5x - 6

I cannot tell what the answers are but I am guessing they are these?:

A) 3x + 2x - 2 - 4

B) 5x - 6

C) 3(x - 4)

D) 3(x + 2) - 6

E) 6(x - 1)

Answer A is one, and so is answer B. If I read your question accurately.

I hope I helped!
