Ok so I wasnt here when we did these so I need help on problems like these:
(b-6)(-5/6)
I also don't really get the "combining like terms" like these:
8b+5-3b
Thx.

So I need a little help on finding the odds because it confuses me. Heres an example of what I mean:
You toss a six-sided number cube 20 times. For twelve of the tosses the # tossed was three or more. What are the odds that a # is tossed is three or more?

Thx.

i get some parts of combining like terms, like 5x+5x, but i need help with combining like terms in an equation like this, x(5+7)+4.

thanks

i still do not fully understand how to simplify by combining like terms. i understand how you are suposed to do it but it never quite works rite,well for me. on page 104 in our book, problem #68 for example -x^3+2x(x-x6^2) like what can u combine?

the distributeave property kind of has been bothering me. i dont get how you group the "like terms" esp, with the variables.

all you have to do is distribute the parantheses in a way that still makes sense while having a different form.

I had trouble with the part about like terms. If there was an exponent ona number I would not know whether to combine the exponents or leave them. My question is what do you do when there are exponents and you are supposed to combine the like terms?

I need a little help when it comes from distributive properties. I need help when we have to make two equations from the figures it gives. EXAMPLE: If you look on page 100 there is an example of two rectangles.
Does anybody have any tips for getting the two equations.

I need help on using an area model with the distributive property. Creating a model confuses me after I know what to do with the distributive property. For example, on page 105, number 86. When you have to make an equation from it, sometimes it is hard to understand.

Hey everybody! I need a little advice on how to make two equations that have to do with distributive property. Here is an example on what problems I need help on.
The is a rectangle with an add on square. The length of the bottem of the rectangle and square put together is 12+x.The side length eqauls 4x. How woud you write the two equations for this situation?

k.a. to r.s. prob
okay I'm pretty sure I know what I'm doing here so for your second problem i know that you take out the 5 and ut it to the side and minus 8b-3b=5b then add 5 so 5b+5 and you can't simplify that any more so your done. For the first problem -5/6=.833 then you have
(b-6)(-.833) and you can distibute that or just have it stay as it is. distributed- b(-.833)+(-5)

i dont know if you want to know how to do the distributive for the first one but i can help you with the second one.

to combine like terms you add terms that have a varriable with the same power. so for your example you would add 5b and -3b.
this gets you 2b. so your equation after combining like terms is 2b+5

I have a problem with the Distributive Property….BIG TIME…
Ok, so when you are given a problem… what are you supposed to do with it?
What are the steps?
I don’t get it at all…

Problem:
3(x+2)

This is what I THINK you do when you are given this problem:

3(x)
=
3x

3(2)
=
6
Which turns out to be….
3x+6=
?????

Help for E.mu- im pretty sur that u DONT combine the exponents... but look in ur book for more help, especially on the top of pg. 102. it helped me!!!

yea thats exactly how you distribute numbers.

I need help…like wat if there is a problem like : (-2 +4) (3 – 4) what would be the # I multiply against the other #’s?

For equatons like this, you need to use the distributive property as well. For x(5+7)+4, you must make x(5+7) into 5x + 7x. This then becomes 13x + 4
Simple as that. Just remember if there are no variables like 5x, you have to use the distributive property to make some!
