To get the next number in a sequence you double the previous number and subtract two.
The fifth number in the sequence is 50.
Find the first number.

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

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
