a square window has a perimeter of (8x + 12) feet. Write an expression that represents the side length of the window. (in feet)
Harrizon [31]
8x+12=p so you would take away 12 from p making the equation 8x=p-12 and then divide that by 8 so the equation is x= p-12/8 ( x equals p minus 12 over 8)

Find the domain of f(x) = Square 3 x + 8 ​
vagabundo [1.1K]

The question is a bit ambiguous: you may mean

\sqrt{3x+8}

or

\sqrt{3x}+8

Anyway, in both cases, the domain of a function involving a square root is found by imposing the content of the root to be greateer than or equal to zero. So, in the first case you have

3x+8\geq 0 \iff 3x\geq -8 \iff x\geq -\dfrac{8}{3}

In the second case, you have

3x\geq 0 \iff x\geq 0
