Find the perimeter of the polygon defined by the coordinates (3, 10), (10, 0), (-1, -2), and (-3, 10). (Round to nearest tenth)

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
