5x-11z=21 48x+4z=92 solve for x

Step-by-step explanation:

20x - 44z = 84

528x + 44z = 1012

548x = 1096

x= 2

48(2) + 4z = 92

96 + 4z = 92

4z = -4

z = -1

(2, -1)

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
