Divide the rational expressions

x/x+1

Step-by-step explanation:

x^2-2x-3/x^2+2x+1 / x-3/x

Factor the left side and flip the divisoin to multipcation

(x+1) (x-3)  * x/x-3

(x+1) (x+1)

The items I bolded are the values that have been canceled, remember u can only cancel when they are multiplying/dividing never do it when adding/subtraction

you are left with : x/x+1

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
