2 answers:
# of seats in a row makes an arithmetic series chairs in the nth row.
an= 4 + 23*5=119
and the sum is
sn= (4+9) * 24/2 = 1476
Answer:
There are 1476 seats in the first 24 rows.
Step-by-step explanation:
The seats at a local baseball stadium are arranged so that each row has five more seats than the row in front of it.
This question is based on arithmetic sequence equation.
Here, a = 4 ; d = 5 ; n = 24
So,
=>
=>
We get An = 119
To get the total seats we will use the formula:
=>
=>
Sn = 1476
Hence, there are 1476 seats in the first 24 rows.

Step-by-step explanation:
Simplify the square root of 54x^9y^7 or √(54x^9y^7)
54x^9y^7 = (3x^4y^3)^2 (6xy)
Now square root of (3x^4y^3)^2 = 3x^4y^3
So the final answer is 3x^4y^3 √(6xy)
