Write a verbal expression for the algebraic expression.

Explanation:

Work out the equation:

1st row is 11 seat and the seat after it will be 6 more and 6 more after the second row and so on. This can be written:

6(x - 1) + 11 =

Where x determine the number of row.

Ex: if x = 1 thus, 6(0) + 11 = 11 seat which is the first row.

Find the number of seats in row 18:

6(18 - 1) + 11
6(17) + 11
= 102 + 11
= 113 seats
