Factorise this :
x(x³ – y³) + 3xy(x – y)​

-by-step explanation:

x(x³ - y³) - 3xy(x-y)= x(x-y)(x²+xy+y²)-3xy(x-y)= x(x-y)(x²+xy+y²-3xy)= x(x-y)(x²-2xy+y²)=

Step-by-step explanation:

wut is this then huh

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
