Solving Quadratic Equations posttest <br><br> A.<br> B.<br> C.<br> D.
beks73 [17]

Answer:

D. x = 3 \pm \sqrt{10}

Step-by-step explanation:

x^2 - 6x - 1 = 0

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

a = 1; b = -6; c = -1

x = \dfrac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-1)}}{2(1)}

x = \dfrac{6 \pm \sqrt{36 + 4}}{2}

x = \dfrac{6 \pm \sqrt{40}}{2}

x = \dfrac{6 \pm \sqrt{4 \times 10}}{2}

x = \dfrac{6 \pm 2 \sqrt{10}}{2}

x = 3 \pm \sqrt{10}

What unit would be best to use for measuring the weight of a stapler?
Alika [10]
<span>The unit that would be best to use for measuring the weight of a stapler are grams. Since a stapler is not too heavy, you don't need a large unit for measurement of weight. Kilograms would be too large, because normally staplers do not weigh a couple of kilograms, but rather a certain number of grams. Hope I helped! :) Cheers!</span>
