Answer:
C. In a meeting room for a business event, there are 4 fewer chairs laid out in each row than the number of rows. The total number of chairs in the room is 60.
Step-by-step explanation:
To find the total number of chars, we multiply the number of rows by the number of chairs in each row.
Let the number of rows be x. There are 4 fewer chairs in each row than the number of rows; this gives us (x-4). Together, this gives us
x(x-4).
We know there are 60 chairs; this gives us
x(x-4) = 60
Using the distributive property,
x(x)-4(x) = 60
x²-4x = 60
