Need answer step by step

(-6, 2)

Step-by-step explanation:

Multiply the second equation by 2

2x - 6y = -24

then add both equations together.

4x + 6y = -12

6x          = -36, divide both sides by 6

x = -6

then plug -6 back into either equation and solve for y

-6 - 3y = -12

-3y = -6

y = 2

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

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
