The first one is it trust me
Total number of seats = 5
Total number of friends = 5
We want to find in how many ways the 5 friends can sit or be arranged in 5 seats. This can be found using permutations.So we are to find the permutations of 5 objects taken 5 at a time. This can be expressed as 5P5.
5P5 = 120
So, the 5 friends can sit in 120 different ways.
The correct answer is option D
Answer:
The answer is opposite/adjacent
Step-by-step explanation:
Based on this saying that SohCahToa
Which means sin=opposite/hypotenuse
Cos=adjacent/hypotenuse
Tan=opposite/adjacent
The opposite is the side facing the right angle
The hypotenuse is the longest side of the triangle
The adjacent is the line that has both the right angle and opposite angle
1. 1x-11. 6x+9 + 5x-20 = 1x-11
2. -2x-11. X-8 -3x-3 = -2x-11
