To find, the length, divide the area by the width:
Length = 20 / 4 = 5 meters.
Given:
The arithmetic sequence is −15, −33, −51, −69.
To find:
The nth term of the arithmetic sequence.
Solution:
We have,
−15, −33, −51, −69
Here,
First term: a = -15
Common difference is



Now, nth term of an arithmetic sequence is

Substitute a=-15 and d=-18.



Therefore, the nth term of the given arithmetic sequence is
.
Answer:
x = 42, y = 36.37
Step-by-step explanation:
Answer:
x = 27
Step-by-step explanation:
Given
- 6 = 2 ( add 6 to both sides )
= 8 ( square both sides )
2x + 10 = 8² = 64 ( subtract 10 from both sides )
2x = 54 ( divide both sides by 2 )
x = 27
