**Ms. Sue**, Thursday, November 3, 2011 at 9:21pmI'll do the first one.

8x + 3 (7x-6)

8x + 21x - 18

29x - 18

I'll be glad to check your answer for the second problem.

**saranghae12**, Thursday, November 3, 2011 at 9:25pmoooh i get the first one now. But wat i am asking is how you do the second problems that are like the second and the third problem.

**Ms. Sue**, Thursday, November 3, 2011 at 9:30pmYou try the second problem. Do it the same way I did the first problem.

**saranghae12**, Thursday, November 3, 2011 at 9:31pmi just want you to know that i might be more confused with this because i am a 7th grader and i am in accelerated math so that is why i am doing 8th grade math and this is really hard for me right now so yeah

**Ms. Sue**, Thursday, November 3, 2011 at 9:32pmIf you can't at least try to do the second problem, you don't belong in accelerated math.

**saranghae12**, Thursday, November 3, 2011 at 9:34pmyeah i did ask my teacher if i could go back to regular math but then she decided that she will decide on my quiz score and i got a good grade

**saranghae12**, Thursday, November 3, 2011 at 9:40pmand for the third problem is it this i will do it in the steps:

4( 1+9x)

4(1)+ 4(9x)

4 + 36x

is this correct?

- 8th grade math -
**Ms. Sue**, Thursday, November 3, 2011 at 9:44pmThe third problem is right.

For the second problem:

-9(4x-8) + 2x

Start by multiplying -9 times 4x and -9 times -8.
