Solve:
-3 ( -4x 1 ) = 13

4/3            (assuming the (-4x 1) is (-4x+1))

Step-by-step explanation:

-3(-4x+1)=13

12x-3=13

12x=16

x=4/3

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
