solve for x:

3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)

x = -1.5.

Step-by-step explanation:

3(7 + 2x) + 3 = 3(5 + x) − 9(x + 1)

21 + 6x + 3 = 15 + 3x - 9x - 9

6x - 3x + 9x = 15 - 9 - 21 - 3

12x = -18

x = -18/12

x = -1.5.

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

if x = 1, then the answer is 3.5
