4x + 5 – 2x = 15. Solve for c

x=5

Step-by-step explanation:

4x + 5 - 2x = 15

2x  + 5 = 15

       -5   -5

2x         = 15

divide 2 on each side

x = 7.5

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
