Answer:
7 2/3
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
Put -1 where x is in each expression and evaluate it.
__
You will find that the expression is zero when the numerator is zero. And you will find the numerator is zero when it has a factor that is equivalent to ...
(x +1)
Substituting x=-1 into this factor makes it be ...
(-1 +1) = 0
__
Evaluating the first expression, we have ...

This first expression is one you want to "check."
You can see that the reason the expression is zero is that x+1 has a sum of zero. You can look for that same sum in the other expressions. (The tricky one is the one with the factor (x -(-1)). You know, of course, that -(-1) = +1.)
First of all, I suppose that you are dividing, /.
Since, you don't have any other symbols here, i.e. + -*.
you work from left to right
444/88 is exactly <span>5.04545454545
</span>5.04545454545/145 is exactly <span>0.03479623824
</span>0.03479623824/140 is exactly <span>0.00024854455
</span>
so the answer to this is <span>0.00024854455
