Step-by-step explanation:
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

Step-by-step explanation:

Answer:
y =
x + 5
Step-by-step explanation:
The Line equation is:
y =
The line equation is in the form of y = m x + c
Slop of this line is (m1) = 
Let another line with slop (m2) , passes through point (4 , 2)
As per question the another line is parallel to the given line equation
So, slop of both the lines are equal
∴ (m2) = (m1) =
Hence equation of another line with slop
and passing through points ( 4 , 2) is
y - y1 = (m2) (y - x1)
I.e y - 2 =
(x - 4)
Or,
Or , 4y - 8 = -3x + 12
Or, 4y = -3x + 12 + 8
Or , 4y = -3x + 20
∴ y =
x + 5
Hence The value of y =
x + 5 Answer
