The area rectangular play ground is a 78 square meters. if the length of the playground is 13 meters what is its width

6 meters.

Step-by-step explanation:

Let w represent width of the rectangle.

We have been given that the area of a rectangle playground is 78 square meters. The length of the playground is 13 meters.

We know that area of a rectangle is width times length of rectangle. We can represent our given information in an equation as:

Therefore, the width of the rectangle is 6 meters.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.
