<u>Given</u>:
The given expression is 
We need to determine the factor of the given expression.
<u>Factor</u>:
Let us rewrite the given expression.
Thus, we have;

Since, the above expression is of the form
, let us apply the identity 
Thus, we have;
------ (1)
Now, we shall factor the term 


Substituting the above expression in equation (1), we have;

Therefore, the factor of the given expression is 
Hence, Option B is the correct answer.
Answer:
D.
The length of the granite must be less than 120 inches.
Step-by-step explanation:
Let x inches be the widht of the section. If the length is 3 times the width, then the length is 3x inches.
The perimeter of the rectangle is

Hence,

The perimeter of the section must be less than 320 inches, so

Answer:
B) 5 (x minus 3)
C) 4 x + 3 y minus 15 minus 3 y + x
E) Negative 20 minus 3 x + 5 + 8 x
tep-by-step explanation:
5x minus 15
5x - 15
5(x - 3)
4 x + 3 y minus 15 minus 3 y + x
4x + 3y - 15 - 3y + x
5x - 15
Negative 20 minus 3 x + 5 + 8 x
-20 - 3x + 5 + 8x
5x - 15
