Answer:
I think the image above will help you a lot.
-x+4(x+3) = 9
Multiplying...
-x+4x+12=9
So,
3x + 12 = 9
Now, subtract 12 from both sides.
3x + 12 - 12 = 9 - 12
3x = -3
Then, divide by 3.
3x/3 = -3/3
x = -1
Answer:
9x^2 - 36x + 36 sq. ft. (the first option).
Step-by-step explanation:
Area of a square of side d = d^2.
So area of this square = (3x - 6)^2
= (3x - 6)(3x - 6)
= 3x(3x - 6) - 6(3x - 6)
= 9x^2 - 18x - 18x + 36
= 9x^2 - 36x + 36 sq ft.
