oh yeah and 4(1 + 9x) can u helo with this one too please
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.
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.
You try the second problem. Do it the same way I did the first problem.
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
If you can't at least try to do the second problem, you don't belong in accelerated math.
ummm is it 6x - 17? im not sure if this is right
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
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?
The third problem is right.
For the second problem:
-9(4x-8) + 2x
Start by multiplying -9 times 4x and -9 times -8.
ooohhh ok so the second problem would be -36x + 72 + 2x right?
Right!
oh i get that now. thank you!
Ooops!
We forgot to add 2x
-34x + 72
oh ok i get it now. thank you!!
You're welcome.
