Answer:

2\sqrt{5v}

Step-by-step explanation:

We can treat 20v as a regular number and not a term.

To simplify this square root, we need to break it down into parts which can be squared.

\sqrt{20v} = \sqrt{4\cdot5v}

Square root of 4 is 2, so that goes outside the radical.

2\sqrt{5v}.

Hope this helped!

40 points for this question! Algebra 2. With all explanation, please!
const2013 [10]
You will need three roots for this, so we have
 Let x = -30, -10 and +20
So the factors will be  (x+30)(x+10)(x-20)
The divide it to 100, this will help bring the peak up and down
So the polynomial function R(x) will become
1/100 *  (x+30)(x+10)(x-20)
R(x) = 1/100 * (x+30)(x+10)(x-20)
 
Finding the X-intercept:
Let R(x) = 0 and solve for x.
1/100 * (x+30)(x+10)(x-20) = 0
x = -30, -10, 20 are the x-intercepts.
