Answer:
A. (2,4)
Step-by-step explanation:
use the substitution method.
for the second equation, subtract x on both sides to get y = 6-x
substitute that into the first equation
6 - x = 3x - 2
add x on both sides: 6 = 4x-2
add 2 on both sides: 4x = 8
divide by 4: x = 2
y = 6-2 = 4
Answer is factored completely: 3x^2(2x^2+5xy^2+y^3
It is B because if you use guess and check plug in 0 for all equations and only B matches with the function.
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
