1/16

the probability of flipping head on the first flip is 1/2

the probability of flipping head on the second flip is 1/2 of that, or 1/4

the probability of flipping head on the third flip is 1/2 of that, or 1/8

the probability of flipping head on the fourth flip is 1/2 of that, or 1/16

I’m a given rectangle the shorter side is 2 units less than the longer side. If we let the longer side be represented as the var
jarptica [38.1K]

Answer:

4(x-1)units

Step-by-step explanation:

In a given rectangle, the length of the rectangle is the shorter side while its breadth is the longer side.

Since we have 2 lengths and 2 breadths in a rectangle, the perimeter of the rectangle will be 2L+2x where

L is the length(shorter side) and x is the breadth (longer side).

According to the question, the shorter side(L) is 2 units less than the longer side(x). Mathematically,

L = x-2

Substituting L = x-2 into the formula of perimeter of a rectangle we have,

P = 2(x-2) + 2x

P = 2x-4+2x

P = 4x-4

P = 4(x-1)

The perimeter of the rectangle will be 4(x-1)units
