Question

A banquet table is formed by placing three square-topped tables edge to edge. The square tabletop of each small table has an area represented by x2−6x+9. What is the overall length of the entire banquet table?

A.
`3x^(2) -9`
B.
`x-3`
C.
`3x^(2) -18x+27`
D
`3x-9`

Answer 1

Option D: 3x - 9

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
