Arectangle has a perimeter of (12+8y). if one side of the rectangle is (4x-2y), write an expression of the other side.

P = 2(l+w)

substitute for P and l

12+8y = 2 (4x-2y+w)

distribute

12+8y = 8x -4y +2w

solve for w

subtract 8x from each side

12 +8y -8x = -4y+2w

add 4y to each side

12 +12 y -8x = 2w

divide by2

6 +6y-4x =w

the other side is 6+6y-4x

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
