-20 in simplest radical form

2√5

Step-by-step explanation:

Here is how to do that! First we write the square root of 20 like this:

√20

The largest perfect square of the factors of 20 is 4. We can therefore convert √20 like this:

√4 × 5

Next, we separate the numbers inside the √ as such:

√4 × √5

√4 is a perfect square that equals 2. We can therefore put 2 outside the radical and get the final answer to square root of 20 in simplest radical form as follows:

2√5

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
