A.[tex]3x^{2} -9[/tex]
B.[tex]x-3[/tex]
C.[tex]3x^{2} -18x+27[/tex]
D[tex]3x-9[/tex]

Answer:

Option D: 3x - 9

Step-by-step explanation:

We are told that A banquet table is formed by placing three square-topped tables edge to edge.

This means means that the 4 sides are equal and the length of the entire banquet table is; 3 x side of the table

Now, the table has an area which is x² − 6x + 9.

Thus, one side will be a factor of the quadratic equation.

From quadratic formula, the factor of the equation is; (x - 3)(x - 3)

Thus,one side is (x - 3).

So, length of entire table is;

L = 3(x - 3)

L = 3x - 9
