The midpoint of ab is m (1,3) . if the coordinates of a are (4,1) , what are the coordinates of b

B(-2,5)

Step-by-step explanation:

Let B (x,y)

M = ([Xa+Xb]/2 , [Ya+Yb]/2)

(x+4)/2 = 1

x+4 = 2

x = 2-4

x = -2

(y+1)/2 = 3

y + 1 = 6

y = 6-1

y = 5

B (-2,5)

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
