Answer:
x^2 - x^3 - 3x^2y - 3xy^2
Step-by-step explanation:
x^3 +y^3 - (x + y)^3
Expand the expression
x^2 + y^3 - (x^3 + 3x^2y + 3xy^2 +y3)
Remove the parentheses
x^2 +y^3 -x^3 -3x^2y -3xy^2 - y^3
Remove the opposites
Answer:
x^2 - x^3 - 3x^2y - 3xy^2
Hope this Helps!
Answer:
84
Step-by-step explanation:
Total students he surveyed: 27

Answer:
r= RE/I
Step-by-step explanation:
E=I(R+r)
divide both sides by I
E/I = R+r
subtract both sides by R
R(E/I) = r
r = RE/I
