The perimeter of a square is 4 times the length of one side.
So, perimeter = 4
Answer:
Subtraction
Step-by-step explanation:
(4x^(5) - 8x) - (3x^(2) - 8x + 9) = 4
x^(
5) - 3
x^
(2) - 9
Assuming that your own ticket is already secured.
From the 5 friends you can only choose 3.
The order in which these friends are chosen is not relevant. So this is a Combination problem.
Where the order is relevant the problem becomes a Permutation problem!
So the answer is 5 combination 3. = ⁵C₃
⁵C₃ = (5 * 4 * 3) / ( 3 * 2 * 1) = 10
You can take 10 groups of any 3 of your 5 friends.

A common
language is needed in order to communicate mathematical ideas clearly and
efficiently. Exponential notation is one example. It was
developed to write repeated multiplication more efficiently. For example, growth
occurs in living organisms by the division of cells. One type of cell divides 2
times in an hour. So in 12 hours, the cell will divide 2 • 2 • 2 • 2 • 2 • 2 • 2
• 2 • 2 • 2 • 2 • 2 times. This can be written more efficiently as
