x = # of balcony seats
y = # of orchestra seats
We have to create a system of equations to solve this problem
x + y = 256
$8x + $12y = $2,716
We will solve this system of equations by elimination.
Multiply the first equation by -8
-8x - 8y = -2048
8x + 12y = 2716
Let's add the equations together
0 + 4y = 668
Simplify the left side
4y = 668
Divide both sides by 4
y = 167
We can subtract 167 from 257 to get the number of balcony seats.
257 - 167 = 90 balcony seats
There are 167 orchestra seats and 90 balcony seats

Answer:
Step-by-step explanation:
f(x)= x^2- 6x + 8 = x² -4x - 2x + 4*2 = x(x-4) - 2(x-4) = (x-4)(x-2)
Real Zeros of this function are 2 and 4
D) g(x) = 2x^2– 12x + 16 = 2 (x^2- 6x + 8)
