Question

The loft Theater has a center seating section with 3c + 8 rows and 4c - 1 seats in each row. Write an expression for the total number of seats in the center section

Answer 1

Explanation:

Number of seats = number of rows * number of seat in each row

= (3c + 8 )*(4c -1)

= 3c*(4c - 1) + 8(4c - 1)

= 3c*4c - 3c*1 + 8*4c - 1*8

= 12c² - 3c + 32c - 8

=12c² + 29c - 8
