so, that function is "defined", ok, what values of "x" are not in the domain, namely, what values can "x" take on and not make the function "undefined", well, you know, if we end up with a 0 at the denominator, like

then, we'd have an "undefined" expression...so... any values of "x" that make the denominator 0, are not really the ones we want, and thus they'd be excluded from the domain.
so, hmm which are those? let's check, let's set the denominator to 0, and solve for "x".
It would help you to make a table because say your answer is 8 pieces is 1 minute and then the next question is how long wouls it take sam to cut 24 pieces you would use the table with you first answer and then multiple both numbers 3 times to give you your answer. Its really just a way to have more organized answers
Answer:

Step-by-step explanation:
Let's examine the following general product of two binomials with variables x and y in different terms:

so we want the following to happen:

Notice as well that
means that those two products must differ in just one unit so, one of them has to be negative, or three of them negative. Given that the product
, then we can consider the case in which one of this (b or d) is the negative factor. So let's then assume that
are positive.
We can then try combinations for
such as:

Just by selecting the first one 
we get that 
and since

This quadratic equation give as one of its solutions the integer: d = -2, and consequently,

Now we have a good combination of parameters to render the factoring form of the original trinomial:

which makes our factorization:

Answer:
8.6
Step-by-step explanation:
5.16 x 10 = 51.6 , 0.6 x 10 = 6, 6 divided by 51.6 = 8.6
