Answer: There are 7 bricks in the first row of the structure.


Step-by-step explanation:

Given function: \(b(r)=7+4(r−1)\) which represents the number of bricks in row r of a structure.

If we put r=1, we get the number of bricks in first row.

\(b(1)=7+4(1−1)\\\Rightarrow\ b(1)=7+0\\\Rightarrow\ b=7\)

Therefore, There are 7 bricks in the first row of the structure.

Thus, the value of 7 represents that there are 7 bricks in the first row of the structure.
