In order to subtract (4x-1) from 4(5x+7), we first need to use the distributive property of multiplication:
[tex]a(b+c)=ab+ac[/tex]So, to calculate the subtraction, we can do the following steps:
[tex]\begin{gathered} 4(5x+7)-(4x-1)\\ \\ =4\cdot5x+4\cdot7-4x+1\\ \\ =20x+28-4x+1\\ \\ =16x+29 \end{gathered}[/tex]Therefore the result is 16x + 29.
