Question

Rhett decides to build a square room for his movie and music collection. If the area of the room is 9x2 - 6x + 1 square feet, what is the length of one side of the room?

Answer 1

Choices.


(9x - 1) feet
(9x + 1) feet
(3x + 1) feet
(3x - 1) feet

Answer 2

area = s^2
9x^2 - 6x + 1 = s^2

s = \(\sqrt{9x^2 - 6x +1}\)
s = \(\sqrt{(3x-1)^2}\)

i leave the rest to you

Answer 3

It is square. so all sides are equal l=w=x. Area will be the product of two sides.
A=9x^2-6x + 1
(3x-1)(3x-1)
3x-1 = length of side.
