Question

Someone help please?

Answer 1

`d = 4n -2 \\d + 2 = 4n\\(1)/(4)d + (2)/(4) = n\\\\n = 0.25d + 0.5`

For a 3-penny nail

`n = 0.25d + 0.5\\ n = 0.25(3) + 0.5\\n = 0.75 +0.5\\\\n = 1.25`

For a 6-penny nail

`n = 0.25d + 0.5\\n = 0.25(6) + 0.5\\n = 1.5 + 0.5\\\\n = 2`

For a 10-penny nail

`n = 0.25d + 0.5\\n = 0.25(10) + 0.5\\n = 2.5 + 0.5\\\\n = 3`

Hope that helped :)
