Prove that: (x-y) (y-z) (z-x)( xy+yz+zx)=|x y z|
|x2 y2 z2|
|yz zx xy|

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

i don’t see a picture

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)

the correct answer would be the third option
