Os pontos A(2; -1), B(-1; 1), e C(0; -4) são vértices não necessariamente consecutivos de um quadrado ABCD. A equação da reta suporte da diagonal AD, desse quadrado, é: x + 5y + 3 = 0
x - 2y - 4 = 0.
x - 5y - 7 = 0
x + 2y - 3 = 0
x - 3y - 5 = 0

answer: the value of x is 7cm

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
