X³+y³=(x+y)(x² - xy +y²)​

➡️x3+y3 = (x+y)(x^2-xy+y^2)

R.H.S

(x+y)(x^2-xy+y2)

=>x3-x^2y+xy^2+x^2y-y^2x+y3

NOW after cancelling we get :

=> x3+y3

L.H.S

=> x3+y3

L.H.S. = R.H.S

Step-by-step explanation:

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
