Answer:
a^3b + 2a^2b^2 + ab^3
Step-by-step explanation:
(a+b)^2
= a^2 + 2ab + b^2
ab(a^2 + 2ab + b^2)
= a^3b + 2a^2b^2 + ab^3
I believe the answer is y= -3
Y = 3
x = -4
(2x + y = -5)3 = 6x + 3y = -15 = 6x + 3y = -15
(3x + 5y = 3)2 = -(6x + 10y = 6) = -6x - 10y = -6
-7y = -21 : y = 3
(then we substitute y into equation #1)
2x + 3 = -5
2x = -8
x = -4
S = 555 I think I’m not 100% sure
