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

The expression of the other side of the rectangle = 2x + 4y + 25

Step-by-step explanation:

The Perimeter of the rectangle is 12 x + 8y

The one side of the rectangle is 4x - 25

Let the other side of the rectangle be S

Now, the PERIMETER OF THE RECTANGLE = 2 ( SUM of BOTH SIDES)

⇒  12 x + 8y =  2(S + (4x - 25))

or, 12 x + 8y =  2S +  8 x - 50

or, 12 x + 8y - 8x + 50 = 2S

⇒ 4x + 8y + 50 = 2S

or, S = 2x + 4y + 25

Hence, the expression of the other side of the rectangle = 2x + 4y + 25

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
