If signs are different you subtract. So 2.5- -1.25 equals 1.25 and keep the sign of the biggest number
Answer:
The common factor is 5x.
The factored polynomial is: 
Step-by-step explanation:
Factor of the numbers:
The common factor of the numbers 5, 30 and 10 is 5, as it is the greater common divisor of them, as found below:
5 - 30 - 10|5
1 - 6 - 2
Factor of the exponents:
Between
and
, the common factor is the x with the lowest exponent. So x
Common factor
Number multiplied by exponents, so 5x.
Factoring the polynomial:

The factored polynomial is: 

<em><u>Solution:</u></em>
Given that,

We have to find whether the above function is odd or even
If a function is: y = f(x)
If f(-x) = f(x), the function is even
If f(-x) = - f(x), the function is odd
Which is,

From given,

Replace x with -x

Therefore,

Thus the function g(x) is even
I'm sorry, but there is not enough information for me to correctly answer this question, please provide more information.
Find the ticket unit cost: divide the total paid, $324, by the number of tickets, x. Then the form of the unit cost is
$324
--------- .
x
This question is highly unusual in that you write "x" as the number of tickets sold, instead of a specific number of tickets. Supposing that you'd sold 100 tickets for $324, then the unit cost would be, much more typically, a numeric ratio:
$324
----------------- = $3.24/ticket
100 tickets
