Answer:

s = 3x - (1/2)y

Step-by-step explanation:

The perimeter of a square is 4s, where s is the side length. Here,

12x - 2y = 4s, and so s = 3x - (1/2)y

Brut [27]

<h2>Answer:</h2> $g(8)-g(-5)=39$

<h2>Explanations:</h2>

Given the function

$g(x)=3x-2$

Get g(8) by substituting x = 8 into the function;

$\begin{gathered} g(8)=3(8)-2 \\ g(8)=24-2 \\ g(8)=22 \end{gathered}$

Get g(-5) by substituting x = -5 into the function

$\begin{gathered} g(-5)=3(-5)-2 \\ g(-5)=-15-2 \\ g(-5)=-17 \end{gathered}$

Take the difference in the result to have;

$\begin{gathered} g(8)-g(-5) \\ =22-\mleft(-17\mright) \\ =22+17 \\ =39 \end{gathered}$

Hence the difference between the given functions is 39
