Answered by Ms. Sue
I'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.
Answered by saranghae12
oooh 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.
Answered by Ms. Sue
You try the second problem. Do it the same way I did the first problem.
Answered by saranghae12
i 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
Answered by Ms. Sue
If you can't at least try to do the second problem, you don't belong in accelerated math.

Answered by saranghae12
ummm is it 6x - 17? im not sure if this is right
Answered by saranghae12
yeah 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
Answered by saranghae12
and 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?
Answered by Ms. Sue
The third problem is right.

For the second problem:

-9(4x-8) + 2x

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

Answered by saranghae12
ooohhh ok so the second problem would be -36x + 72 + 2x right?
Answered by Ms. Sue
Right!
Answered by saranghae12

Answered by Ms. Sue

We forgot to add 2x

-34x + 72
