NEED HELP ASAP TODAY!!! IF YOU GET IT RIGHT THEN ILL MARK YOU BRAINLIEST!!!

Answer:
(x-6)
Step-by-step explanation:
To figure out the length of one side you need to first understand that to find the area you must use the formula A = l x w. Since the shape is a square, the side length should be the same for all sides. For this specific problem, all you would need to do is factor [tex]x^2-12x+36[/tex].
To factor [tex]x^2-12x+36[/tex], you need to determine what two numbers add together to get -12and multiply to 36. These two numbers are -6. You would then need to fill in the blanks in (x+_)(x+_) with -6 and -6 to get (x-6)(x-6). Since it is only asking for one side, the answer would be (x-6)
Answer:
Side length = x - 6
Step-by-step explanation:
x² - 12x + 36 The expression for the area of the square
Remember the formula for area of a square is A = s² (Area is side squared).
s² = s x s
To find the length of one side, we need to change x² - 12x + 36 into an expression with two factors multiplying each other. This is done by factoring.
x² - 12x + 36 is a special type of trinomial called a perfect trinomial. To factor perfect trinomials, follow this rule:
ax² ± bx + c = (√(ax²) ± √(c))² = (√(ax²) ± √(c)) (√(ax²) ± √(c))
Take the square root of the first and last terms, then take the positive/negative sign of the middle term.
Square root of first term: √x² = x
Square root of last term: √36 = 6
Sign of middle term: (-) negative
x² - 12x + 36 = (x - 6)² = (x - 6)(x - 6)
Apply the formula for area to the factored form.
A = s² = (x - 6)²
Since "s" is the side, one side is x - 6.
