Add 4x to both sides of the equation to get the equation into a form that can be graphed. rearrange the equation to regular form into y= -x^2 -4x +7 and put it into ur graphing calculator. look for the halfway of the parabola that would fold it in half

Answer:
80 persons haf fish and 152 persons had chicken
Step-by-step explanation:
Given data
let the number of persons that had fish be x and chicken be y
so
12x+9y=2544------------------1
x+y= 232------------------------2
from 2
x= 232-y
substitute the value of x in 1
12(232-y)+9y=2544
2784-12y+9y=2544
2784-3y=2544
3y= 2784-2544
3y=240
y= 240/3
y=80
put y= 80 in 2
x+80= 232
x= 232-80
x=152
Hence 80 persons haf fish and 152 persons had chicken
A cube because it’s already square n can be cut in square cross sections
