The area of any rectangle shape is given by the product of its width and length. If the area of a particular rectangular garden is given by A=15x^2 -35x and its width is given by 5x

Question

Find an expression for the garden's length.explain

Answer 1

So Area = length * width. Substitute in the expressions

15x² - 35x = length * 5x

We can factor out the left hand side.

5x(x - 7) = length * 5x

Dividing by 5x gives:

x - 7 = length
