Answer:
3,267
Step-by-step explanation:
Fro the statement you can write the following equations:
x+y= 4,356 (1)
y= 3x (2)
x= afternoon perforance
y= evening perforance
Then, you can replace 2 in 1 and isolate x:
x+3x= 4,356
4x= 4,356
x= 4,356/4= 1,089
y= 3x= 3(1,089)= 3,267
According to this, the answer is that for the evening performance 3,267 tickets were sold.

The correct answer is: Option (D) Take the square root of both sides
Explanation:
Given equation:
9x^2 -24x + 16 = 11
Step 1:
9x^2 - 12x - 12x + 16 = 11
3x(3x - 4) - 4(3x - 4) = 11
(3x-4)^2 = 11
Step 2:Take square-root on both sides (Option D)
![\sqrt{(3x-4)^2} = \sqrt{11}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%283x-4%29%5E2%7D%20%3D%20%20%5Csqrt%7B11%7D)
![(3x-4) = \sqrt{11} \\ x = \frac{ \sqrt{11} + 4 }{3}](https://tex.z-dn.net/?f=%283x-4%29%20%3D%20%5Csqrt%7B11%7D%20%5C%5C%20%20x%20%3D%20%20%5Cfrac%7B%20%5Csqrt%7B11%7D%20%2B%204%20%7D%7B3%7D%20)
(value of x)
