Find the length x (I'm giving 10 points if you answer this question wrong just to get the 10 points I will report your account)
Natali5045456 [20]
Okay so here's how i think you solve it


both triangles have the same ratio, so set it as 3/4.5 (the smaller triangle) is equal to X/13.5 (the 9 added to the 4.5)

multiply 13.5/1 on both sides to get x alone

13.5 3
-------- x ------- = x x= 9
1 4.5

Please help? Graph <img src="https://tex.z-dn.net/?f=-3x%5E2%2B12y%5E2%3D84" id="TexFormula1" title="-3x^2+12y^2=84" alt="-3x^2+
mariarad [96]
-3x^2+12y^2=84
12y^2=3x^2+84
y^2=\dfrac{x^2}4+7
y=\pm\sqrt{\dfrac{x^2}4+7}

For either square root to exist, you require that \dfrac{x^2}4+7\ge0. This is true for all x, since \dfrac{x^2}4 is always non-negative. This means the domain of y as a function of x is all real numbers, or x\in\mathbb R or (-\infty,infty).

Now, because \dfrac{x^2}4+7 is non-negative, and the smallest value it can take on is 7, it follows that the minimum value for the positive square root must be \sqrt7, while the maximum value of the negative root must be -\sqrt7. This means the range is y\in\mathbb R\setminus(-\sqrt7,\sqrt7), or |y|\ge\sqrt7, or (-\infty,-\sqrt7]\cup[\sqrt7,\infty).

Pull out a 5 from the first parenthesis
(5x+15) = 5(x+3)

Pull out a 25 from the second parenthesis
(25x+75) = 25(x+3)

(5x+15) + (25x+75) = your first answer = 5(x+3) + 25(x+3)
