Answer 1

Answer:

The answer to"the function b(r)=7+4(r-1) represents the number of bricks in a row r of a structure" is D

Answer 2

I think it's C. There are 7 bricks in the first row of the structure.

Given the function: b(r) = 7 + 4(r-1), r is the row of the structure.

Find b, when r = 1. How many bricks are in row 1?

b(1) = 7 + 4(1-1)

b(1) = 7 + 0

b(1) = 7

Answer: C.
