The number of rows in the arena is 26
<h3>How to determine the number of rows?</h3>
The hockey arena illustrates an arithmetic sequence, and it has the following parameters:
- First term, a = 220
- Sum of terms, Sn = 10920
- Common difference, d = 16
The number of rows (i.e. the number of terms) is calculated using:
So,we have:
Evaluate the terms and factors
Evaluate the like terms
21840 = n(424+ 16n)
Expand
21840 = 424n + 16n^2
Rewrite as:
16n^2 + 424n - 21840 = 0
Using a graphical tool, we have:
n = 26
Hence, the number of rows in the arena is 26

Answer:
360
Step-by-step explanation:
T = K(1/H)
Whereas T = seconds
H = cooker setting
K = the constant of proportionality
T = (240/6)/(1/9) = (240/6)x9 = 360
All ya got to do is break is down
Step 1) 4y(2y2+3y-5)-3(2y2+3y-5)
Step 2) 8y3+12y2-20y-3(2y2+3y-5)
Step 3) 8y3+12y2-20y-(6y2+9y-15)
Step 4) 8y3+12y2-20y-6y2-9y+15
Step 5) 8y3+(12y2-6y2)+(-20y-9y)+15
Then you got to simplify and you have to
Leave the
8y3 +
12-6= number y2 -
-20-9=- number y
Then leave the 15
Sorry your doing the same math as me so I get carried away :p
