Answer:
(x-6)^2 =40
Step-by-step explanation:
The correct answer is (x-6)^2 =40
why??
Expand (x-6)^2
x^2 -12x+36 =40
Transpos 40 to the left side
So,
x^2 -12x+36 -40
Which is
x^2 -12x -4=0

1/4 cups of butter
because 3/4 times 1/3 =
1/4
Step-by-step explanation:
27^x / sqrt(9^y) = 3 and log2(x) - 2 = log2(y).
3^3x / 3^y = 3 and log2(x) - log2(4) = log2(y).
3x - y = 1 and x/4 = y.
Therefore x = 4/11 and y = 1/11.
