If the area of a rectangular garden is 45x2−12x square meters, and it has a length of 3x meters, what is its width?

Respuesta :

sqdancefan

Answer:

  (9x -4) meters

Step-by-step explanation:

The relationship between area, length, and width is ...

  area = length × width

Dividing by length gives ...

  width = area/length

Filling in the given expressions, we have ...

  [tex]w=\dfrac{45x^2-12x}{3x}=\dfrac{45x^2}{3x}-\dfrac{12x}{3x}=9x-4[/tex]

The width of the garden is 9x-4 meters.

Answer:

15x-4

Step-by-step explanation:

Like the previous answer, AREA= length*width

We are given the area, which is 45x^2 - 12x. We are also given the length which is 3x. Using long division, we see (45x^2 - 12x)/3x.

The answer, which is the width, is 15x-4.
