Using synthetic division, find (2x^4 - 3x^3 - 20x -21) + (x-3).

Step-by-step explanation:

i think you want to know if x-3 is a factor.

x-3=0

x=3

3 ) 2  -3  -20  -21

  |       6   9    -33

  |

     2   3  -11  |-54

remainder is not zero,it is -54

so x-3 is not a factor of 2x^4-3x²-20x-21

the answer is c

hope this !

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
