¿Cuál es el valor de 36x - 8y? cuando x = 3 y y = -6? A. -288
B. -180
C. 1,200
D. 3,600
O

156

Step-by-step explanation:

Tienes que cambiar los valores de las letras por el número que te indica

x=3  y=-6   36x-8y

Entonces:

36(3)-8(-6)

108+48

156

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
