Option C: (x+4) and (x-1) are the factors of the equation
Explanation:
Given that the equation is 
We need to determine the factors of the equation.
Splitting the middle term, we get,

Grouping the terms, we have,

Let us factor out the term (x+4), we have,

Thus, the factors of the equation are (x+4) and (x-1)
Hence, Option C is the correct answer.
For this case we have the following expression:

By definition, a coefficient is the term that accompanies one or more variables.
For example:

The coefficient of the linear term is 3.
So, in the given expression we have to:
-4 is the term that accompanies the variables xy.
Answer:
-4
-7.08 as a fraction in simplest form would be -177/25
Answer:
8x+y
Explanation:
3x+4y+5x-3y
Rearrange the terms so like terms are next to each other
3x+5x+4y-3y
Combine like terms
8x+y
I hope this helps!
