C+A=342
$5C+$12A=$2,550
5C+5A=1710
5C+12A=2550
-7C=-840
C=120
5(120)+12A=2550
600+12A=2550
12A=1950
A=163
I do not believe so, because a square is in the rectangle family. If a rectangle was in the square family, it would have to have all sides the same length, wich wouldnt make it a rectangle anymore.
let the 2 integers be x and x + 2.
so we have the equation:-
3(x + 2) = x - 10
3x + 6 = x - 10
2x = -16
x = -8
the integers are -8 and -6 answer
Y = (x - 5)²
y = (x - 5)(x - 5)
y = (x² - 5x - 5x +25)
y = x² -10x + 25
