Answer:

<h2>      x₁ = - 2 + √2 ,   x₂ = - 2 - √2</h2>

Step-by-step explanation:

3x^2 + 12x + 6 = 0\\\\a=3\,,\ b=12\,,\ c=6\\\\\\ x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\ x=\dfrac{-12\pm\sqrt{12^2-4\cdot3\cdot6}}{2\cdot3}=\dfrac{-12\pm\sqrt{144-72}}{2\cdot3}=\dfrac{-12\pm\sqrt{72}}{2\cdot3}=\dfrac{-12\pm6\sqrt{2}}{6}\\\\x_1=\dfrac{6(-2+\sqrt{2})}{6}=-2+\sqrt2\\\\x_2=\dfrac{6(-2-\sqrt{2})}{6}=-2-\sqrt2

Answer:

46.2 square inches

Step-by-step explanation:

A parallelogram is a quadrilateral (4 sided closed figure) with 2 pair of parallel sides.

The diagram shown is a parallelogram.

Top and Bottom are parallel lines,

both sides are parallel lines (left and right).

The area for a parallelogram is given by:

Area = Base * Height

In the given figure, the base is clearly given as 4.2 inches

The height (perpendicular distance from base) is given as 11 inches.

<em><u /></em>

<em><u>So, basically we do not need the 11.7 inches length of side given.</u></em>

<em><u /></em>

Now, lets compute the area:

Area = base * height = 4.2 * 11 = 46.2 square inches

If the probability is 0.54 that Stock A will increase in value during the next month and the probability is 0.68 that Stock B wi
Aloiza [94]

P(A) =0.54

P(B)= 0.68

P'(A)= 1-0.54 = 0.46

P'(B)= 1- 0.68 = 0.32

The probability of neither of both event will occur:

= P'(A)×P'(B)

=0.46 × 0.32

=0.1472
