B. (9x − 1) feet

D. (9x + 1) feet

I am stuck on this question please help thank you

Answer 1

it is supposed to say 9x^2-6x+1

Answer 2

Since it is a perfect square, it's easy to check.

(a-b)^2 = a^2-2ab+b^2

so you know that a=3 and b=1

(3x-1)^2 = 9x^2-6x+1

Answer 3

so it would be c?

Answer 4

Yes, C is correct
