The three integers can be anything that leads down to the product of negative 4 or -4 is negative -2 x -1 x -2 i think this is it since i am also learning about this in 7th grade k12
If the unknown number is x then the equation is:
25x/45=-65
Solution
5x/9=65
5x=-65*9
5x=-585
5x/5=-585/5
x=-117
It only works if C is the midpoint of AB
The sides
12-3a
12-3a
4(2a-5)=8a-40
so for perimeter we + them
(12-3a)+(12-3a)+(8a-40)
=
2a-16
