Solving Quadratic Equations posttest A. B. C. 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

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

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

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

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

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

$x = 3 \pm \sqrt{10}$

The area of the rectangular garden is 38 1/4 square meters the width of the garden is 4 1/2meters find the length of the garden

faltersainse [42]

Answer:

Area = Length * Width

38 1/4 = L * 4 1/2

L = (38 1/4)/(4 1/2) = (153/4)/(9/2) = (153 * 2)/(4 * 9) = 17 1/2

What unit would be best to use for measuring the weight of a stapler?

Alika [10]

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!
