Answer:
To do this, you need to multiply out the expressions. This is a bit tedious, but remember like FOIL for binomials, for these trinomials you must multiply each term. If you need a step-by-step, I'd be happy to provide it. Let me know.
Once you have simplified the expression, you get
-x-9/2x-4
But, the problem stipulates that a must equal 1. We can equivalently factor out the negative sign and put it on the denominator with no change to write
x+9/-(2x-4) = x+9/-2x+4
So, seeing where each coefficient corresponds between the two expressions, you get a = 1, b = 9, c = –2, and d = 4.

Answer:
C
Step-by-step explanation:
Perimeter of a triangle is the sum of all the sides.
A triangle has 3 sides, so if we add up all the 3 sides lengths <em>(given as expressions here)</em> of the triangle, we will have the perimeter.
Perimeter = 
<em>Now combining like terms we have:</em>
<em>
</em>
Answer choice C is the correct one.
