    Answer:

    27

    Step-by-step explanation:

    X=1

    Y=-2

    (iii)(x+y-2xy)(x-4y+xy)

    =>{1-2-2(1)(-2)} {1-4(-2)+(1)(-2)}

    =>{1-2+4} {1+8-2}

    =>{5-2} {9-2}

    =>{3}{7}

    =>27

    Hope this helps✌️

    Answer:

    The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a complex number: x is the real part and y is the imaginary part: x+yi. (x,y) has the meaning of a plane’s vector from origin of coordinates.Aug
