The midpoint of AB is M(0, -3). If the coordinates of A are (6, -5), what are the coordinates of B?

(-6,-1)

Step-by-step explanation:

let b be x2,y2

then apply mid point formula

x=(x1+x2)/2

y=(y1+y2)/2

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

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
