Answer:

  B.  8xy²√(2x) cm

Step-by-step explanation:

First of all, you need to know the area of a square is the square of its side length.

   A = s²

Then the side length is the square root of the area.

  √A = s

You are given the area and asked for the side length, so you need to take the square root of the given expression. To put the result in simplest form, you need to remove all the squares from under the radical.

s=\sqrt{128x^3y^4\, cm^2}=\sqrt{(8xy^2\, cm)^2\cdot 2x}=8xy^2\sqrt{2x}\, cm

Is there a relationship between the area and the perimeter of a rectangle
maksim [4K]
Well, an area and perimeter have formula's. The formula of area is length times width. The formula of perimeter is to basically length plus length plus width plus width. For instance, let's say the rectangles width is 5 and length is 6. So you do 5 plus 5 which is 10 and then 6 plus 6 which is 12. And then, 12 plus 10 equals 22. So the perimeter would be 22. If you were to find the area, you would do 6 times 5 and the area would be 30.
I hope this helps :)

The vector ab has a magnitude of 20 units and is parallel to the<br> vector 4i + 3j.<br> find ab.
stepladder [879]

The vector ab has a magnitude of 20 units and is parallel to the

vector 4i + 3j. Hence, The vector AB is 16i + 12j.

<h3>How to find the vector?</h3>

If we have given a vector v of initial point A and terminal point B

v = ai + bj

then the components form as;

AB = xi + yj

Here, xi and yj are the components of the vector.

Given;

The vector ab has a magnitude of 20 units and is parallel to the

vector 4i + 3j.

magnitude

\sqrt{4^2 + 3^2} \\\\\sqrt{16 + 9} \\\\= 5

Unit vector in direction of resultant = (4i + 3j) / 5

Vector of magnitude 20 unit in direction of the resultant

= 20  x (4i + 3j) / 5

= 4 x (4i + 3j)

= 16i + 12j

Hence, The vector AB is 16i + 12j.
