Roots: - √5 , √5, and - 3
=> these are factors of the polynomial: (x + √5), (x - √5), and (x + 3).
Multiply those three factors:
(x + √5) (x - √5) ( x + 3) = [x^2 - 5] ( x + 3 ) = x^2 + 3x^2 - 5x - 15
Therefore the polynomial x^2 + 3x^2 - 5x - 15 is a polynomial with the given roots.
Answer: option B. x^3 + 3x^2 - 5x - 15
(3x-2)(x+1)
3x*x+3x-2x-2
3x^2+3x-2x-2
3x*2+x-2
I think this is the answer
I think the answer is 20.34 I might be wrong someone else could check

We have been given an equation
that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.
To solve our given problem, we will substitute
in our given equation as:

Let us solve for t.





Therefore, it will take
hours Joe to paint 7 walls.
