Answer: 
Step-by-step explanation:
We have the following polynomial:
This is a polynomial of the form 
. Following this rule to expand it, we have:
Applying common factor 
:
Note the polynomial inside the parenthesis is a perfect square trinomial, which can be factored to
. Hence, the final simplification is:
((x^2-3x-18)/(x+3))
((x-6)(x+3))/(x+3)
The x+3 on top cancels out the x+3 on the bottom so all you have left is
x-6
Hope I didn't mess up for your sake!
(-9)+(-6)+(-4)+(-1) is the expression and (-20) is the sum
Answer:
<h2>C. 5/9</h2><h2 />
Step-by-step explanation:
10x = 5.5
<u> -x = 0.5</u>
9x = 5
x = 5/9
therefore, the answer is C. 5/9
