Answer 1

Step-by-step explanation:

=3 (x2-9)----------------------------------------------------------------- =3 (x2-3^2)--------------------------------------------------------------- =3 (x+3)(x-3)-------------------------------------------------------------- Therefore l=3, b=x+3, h=x-3

Answer 2

Answer: 3, (x-3), (x+3)

Step-by-step explanation:

3x^2-27

=3(x^2-9)

=3(x^2-3^2)

=3(x-3)(x+3)

Therefore, the dimensions are 3, (x-3) and (x+3)
