The width of a rectangle is 6 x - 2 feet and the length is 3 x + 6 feet. find the perimeter of the rectangle.

hello :

Find the perimeter of the rectangle is : p = 2( w +l)

p = 2 (6x-2 + 3x+6)

p = 2(9x +4)

p = (18x + 8 ) feet

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)

ou would have 12 of each
