It was a very freaky weather day. the temperature started out at 12 in the morning and dropped 21 by noon. it stayed at the temperature for six hours and then rose 5 .write a numerical expression that would represent the temperature at 6 p. m. then solve

12-21+5=-4

Step-by-step explanation:

12-21=-9

-9+5=-4

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
