The problem given above can be solved through the concept of permutation because of the importance of the arrangements. This may be solved through calculators directly by keying in,
10P5
That is, the permutation of 10 taken 5. The answer to this permutation is 30,240.

15x+15 ?
Step-by-step explanation:
Answer:
5k+17
Step-by-step explanation:
Combine like terms. Like terms are terms such as 10 and 7. Some caome with variables, such as 5k and 6k. 10+7 is 17. Since you can't combine unlike terms, the expression becomes 5k+17.
Three lines creating six angles
3 angles on top, 3 angles below
Since the top left angle is a right angle
It means the line that divides the top angles from the angles below is bisected by a perpendicular line.
This means the sum of the angles of the top left = 90°
Therefore, x + 61° = 90°
x = 90° – 61°
x = 29°
