Give me some options please so I can answer the question
B. -3
The value of a for given polynomial is -3
<h3>
Explanation:</h3>
<em>Factor theorem for polynomials,</em>
<u><em>If (x-c) is a factor of polynomial f(x), then f(c)=0</em></u>
Given: x+a is a factor of polynomial 
Let 
By Factor theorem, since x+a is a factor of f(x),
![(x+a)=[x-(-a)]\\So,\ f(-a)=0](https://tex.z-dn.net/?f=%28x%2Ba%29%3D%5Bx-%28-a%29%5D%5C%5CSo%2C%5C%20f%28-a%29%3D0)
Substituting 
in f(x)=0, we get
![f(x) = 4x^3-13x^2-ax = 0\\f(-a)= [4(-a)^3]-[13(-a)^2]-[a(-a)] = 0\\(-4a^3-13a^2+a^2)=0\\(-4a^3-12a^2)=0\\-4a^3=12a^2\\\frac{a^3}{a^2} =\frac{12}{-4} \\\\a=(-3)](https://tex.z-dn.net/?f=f%28x%29%20%3D%204x%5E3-13x%5E2-ax%20%3D%200%5C%5Cf%28-a%29%3D%20%5B4%28-a%29%5E3%5D-%5B13%28-a%29%5E2%5D-%5Ba%28-a%29%5D%20%3D%200%5C%5C%28-4a%5E3-13a%5E2%2Ba%5E2%29%3D0%5C%5C%28-4a%5E3-12a%5E2%29%3D0%5C%5C-4a%5E3%3D12a%5E2%5C%5C%5Cfrac%7Ba%5E3%7D%7Ba%5E2%7D%20%3D%5Cfrac%7B12%7D%7B-4%7D%20%5C%5C%5C%5Ca%3D%28-3%29)
Therefore, value of a is (-3)
Forming political organizations, Women's organizations that helped lead the way in the abolition movement.
Answer: Option B & D
<u>Explanation:</u>
Philadelphia was an American region that was rich in abolitionist heritage. It launched various political organizations to fight in the antislavery struggle. Philadelphia was suffered from slavery for nearly a hundred and fifty years. It becomes the seedbed for the abolitionist thoughts within the people.
That, in turn, led to the creation of the political organizations that supports the abolition of slavery such as the Pennsylvania Abolition Society, American Anti-slavery Society Convention, etc. Also, Women contributed more to radicalism by starting abolitionist organizations.
Philadelphia Female Anti-slavery Society and the Anti-Slavery Convention of American Women were some of the women organizations that served as the backbone of the abolitionism.
Sparta was focused on military training, and Athens on academics. Maybe you ran into Socrates the philosopher in Athens, and he started asking you odd questions. Or perhaps you noticed children being matched out of Sparta as you entered, possibly to be made to (if the rumors are true) fight wolves in the wilderness. You likely noticed the red plumes on Spartan helmets, and the blue on Athenian ones if any.
Do you have any answer choices? If you do, it would most probably be they all founded colonies
