Answer:
In standard form it is x^4 - 12x^3y + 54x^2y^2 - 108x y^3 + 81y^4.
Step-by-step explanation:
(3y)^4 + 4C1(3y)^3(-x) + 4C2(3y)^2(-x)^2 + 4C3(3y)(-x)^3 + (-x)^4
= 81y^4 - 108y^3x + 54y^2x^2 - 12yx^3 + x^4

Answer:
16 = 3x
Step-by-step explanation
Find the diagram attached.
Perimeter = sum of all its sides
Sum of all its sides= x+x+x
Sum of all its sides = 3x
Given perimeter = 16in
Equating both;
3x = 16
x = 16/3
x = 5.33in
Hence the value of x is 5.33 and the required equation is 16 =3x
It’s sum is 456 and it’s opposite is 654
56=(x+2)x(2x-5)
56=2x^2-5x+4x-10
56=2x^2-x-10
0=2x^2-x-66(use midterm breaking now)
0=2x^2+11x-12x-66
0=2x(x-6)+11(x-6)
So factors are (2x+11) or (x-6) as the length is always positive we chose x-6 so x-6=0..x=6 is the answer thanks now plz select answer as brainliest :)
