John made a rectangle pen for his dog using 28 feet of fencing. if the width of the two more than one-half the length what is the length and width of the pen the length i’ve pen is

The length of the pen is

The width of the pen is

Step-by-step explanation:

Let

x-----> the length of the pen

y----> the width of the pen

we know that

The perimeter of the pen is

so

------> equation A

-----> equation B

Substitute equation B in equation A and solve for x

Find the value of y

therefore

The length of the pen is

The width of the pen is

(- 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 )
