What is the answer to 8.5+4(1-2.5k)=-24.5

CaHeK987 [17]

8.5+(4×1)+(4×-2.5k)=-24.5
8.5+(4)+(-10k)=-24.5
(8.5+4)+(-10k)=-24.5
12.5+(-10k)=-24.5
-10k=-24.5-12.5
-10k=-37
k=-37/-10
k=37/10

42. Use the Quadratic Equation to find the Roots of x2 + 3x - 3 = 0

Ierofanga [76]

Answer:

<h2> Roots: 0.79 and 3.79</h2>

Step-by-step explanation:

$x^2 + 3x - 3 = 0\\a=1\,,\ \ b=3\,,\ \ c=-3\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\dfrac{-3\pm\sqrt{3^2-4\cdot1\cdot(-3)}}{2\cdot1}=\dfrac{-3\pm\sqrt{9+12}}{2}=\dfrac{-3\pm\sqrt{21}}{2}\\\\x\approx0.79\quad or\quad x\approx3.79$
