Arectangle has sides of 4x cm and x cm. the sides of the rectangle are all increased by the same length. if the perimeter of the larger rectangle is 10x + 16, what is the length added to each side, in centimeters?

  4 cm

Step-by-step explanation:

The perimeter of the original rectangle is ...

  P = 2(L+W) = 2(4x + x) = 10x

The perimeter of the larger rectangle after we add "a" to each side is ...

  P = 2(L +W)

  = 2((4x+a) +(x+a))

  = 10x +4a = 10x +16

  4a = 16 . . . . . subtract 10x from both sides

  a = 4 . . . . . . . divide by 4

The length added to each side is 4 cm.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
