<span>There are 4 long rows and 5 short rows in the theater. x represents the number of chairs in each long row and y represents the number of chairs in each short row.
So, total number of chairs in 4 long rows= 4x
Total number of chairs in 5 short rows = 5y
Total number of chairs in the theater on a normal day = 4x + 5y
When 2 chairs are added to each long row, the number of chairs will change to (x+2).
So, total number of chairs in 4 long rows will be = 4(x+2)
When 3 chairs are added to each short row, the number of chairs will change to (y+3)
So, total number of chairs in 5 short rows will be = 5(y+3)
Thus, total number of chairs in the theater in rush day = 4(x+2) + 5(y+3)
= 4x + 8 + 5y + 15
= 4x + 5y + 23
Thus we can say the number of chairs increase by 23 as compared to a normal day.

Answer:
a
Step-by-step explanation: thank me later
This is when you would "combine like terms." All variables together, all numbers together.
So... -2 and 8
6y and -2y
M and -4m
6 is the solution to ine
4y is the second
-3m is the third
Therefore, the answer is 6 + 4y + -3m
<u>Answer</u>
1
<u>Explanation</u>
The general equation of a wave is ;
y = a sin(kX+Ф)
Where a represent the amplitude, 360/k represent the period of the wave and Ф represent the phase angle.
∴ In the equation y = 1 sin 2x,
Amplitude = 1
