Mia spent 6 hours studying for an exam, and she received an A on the exam. Normally, she would have spent that time watching TV instead of studying. Mia figures she could have made a B after studying only 3 hours, but she really wanted an A. What is Mia ’s marginal cost in terms of TV viewing to move from a B to an A on the exam?

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

the value of x is 28.2

your answer would be b
