Wich pair of equations below represents perpendicular lines? !

B) y = 5x + 15 and y = -5x + 15 I think.

It is A

Step-by-step explanation:

it is the negative recipricol

30

step-by-step explanation:

times by times

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
