Evaluate the polynomial f(x) =2x^3-4x^2+2x-8. At x=-2

f(- 2) = - 44

Step-by-step explanation:

Substitute x = - 2 into f(x) and evaluate, that is

f(- 2) = 2(- 2)³ - 4(- 2)² + 2(- 2) - 8

        = 2(- 8) - 4(4) - 4 - 8

        = - 16 - 16 - 4 - 8

        = - 44

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
