Hallar el area y perimetro de un poligono definido por los puntos A(3,5),B(6,-6),C(-2,-4)y D(8,7).​

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
