(i raised the points and i will give brainliest its also multiple choice )
the function b(r)=7+4(r-1) represents the number of bricks in a row r of a structure

what does the value 7 represent in this situation?

a) every row contains exactly 7 bricks

b)the structure contains 7 rows of bricks

c)there are 7 bricks in the first row of the structure

d)a given row of bricks contains 7 more bricks than the previous row

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

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

C.

//Hope it helps.

could you reply to this with the question so i can ?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
