7more than a number is the same as 2 times the number minus 11

18

Step-by-step explanation:

7 + N = 2 * N - 11

+11 both sides

N + 18 = 2 * N

-N both sides

18 = N

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
