Step-by-step explanation:

(3x^2-2x-8)-(3x^2 -4x +3 )

3x^2 - 2x - 8 - 3x^2 + 4x - 3

2x-11

answer: 1 and 3

step-by-step explanation:

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
