20 POINTS!! Betty arranged equal numbers of movies on four shelves of a shelving unit and placed 6 of her favorite movies on the top shelf. If x is the number of movies on each shelf, the expression for the total number of movies on the shelving unit is 4x + 6.

If each of the 4 shelves holds 12 movies, how many movies does Betty have on her shelving unit? Show your work.

54 movies

Step-by-step explanation:

shelving unit has 4x + 6 movies

and  each  holds 12 movies,

then x =12

Then solve 4x + 6  for x= 12

4(12) + 6 = 54

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

14.29%
