The length of a rectangle is 1 meter less than its
width. The area of the rectangle is 42 square
meters. Find the dimensions of the rectangle.

If the length of the rectangle is x, then we know the width is x + 1.

The area of a rectangle is length · width, so we can substitute as x · (x + 1)

Now, we now x · (x + 1) = 42

Expand

x² + x = 42

Solve

x² + x - 42 = 0

(x + 7)(x - 6) = 0

So, x = 6

That means the length is 6 meters and the width is 7 meters.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
