- expand the polynomials - (x^(2)+xy-y^(2))(x+y)

(b-c)(b^2-bc-c^2)

(a^2-2a+3)(a-4)

(5x-2)(x^2-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
