line BF contains point B and as you can see, it not only does not intersect CD, but it also goes in a different direction, thus, these lines are in different planes, thus, the lines are skew.

So line BF is the correct option.

<h3>Which line contains point B and seems to be skew to CD?</h3>

We say that two lines are skew if the lines are not parallel and do not intersect.

For example, the line BC clearly contains the point B, but by looking at the diagram we can see that the line BC intersects the line CD, so these lines are not skew.

In other hand, line AB also contains point B, but this line is parallel to CD, so we discard this one also.

Line AE does not contain the point B, so also can be discarded.

Finally, line BF contains point B and as you can see, it not only does not intersect CD, but it also goes in a different direction, thus, these lines are in different planes, thus, the lines are skew.

So line BF is the correct option.

What is the solution set of 2x(x - 1) = 3?

garik1379 [7]

First you must distribute the 2x to the numbers inside the parentheses

(2x * x) + (2x * -1) = 3

$2x^{2}$ - 2x = 3

To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides

$2x^{2}$ - 2x - 3 = 0

Use the quadratic equation to solve this (image of the quadratic equation is below)

Remember that quadratic functions are set up like so:

$ax^{2} +bx +c = 0$

That means that in this equation...

a = 2

b = -2

c = -3

^^^Plug these numbers into the quadratic equation and solve...

$\frac{2+/-\sqrt{(-2)^{2}-4(2)(-3)}}{2(2)}$

$\frac{2 +/-\sqrt{4+24}}{4}$

$\frac{2+/-\sqrt{28} }{4}$

$\frac{2+/-2\sqrt{7} }{4}$

$\frac{1+/-\sqrt{7} }{2}$

Keep in mind that +/- is ±

$\frac{1+\sqrt{7} }{2}$

$\frac{1-\sqrt{7} }{2}$

6 sided cube rolled( probability of p(4)

Debora [2.8K]

Answer:

1/6

Step-by-step explanation:

The probability of rolling a 4 on a 6-sided die is 1/6 because there is a fair chance that any of the numbers from 1 to 6 are chosen, and 4 is one number out of 6 possible numbers that could be chosen.

Suppose you have abc with ab = 5, bc = 7, and ca = 10, and also efg with ef = 900, fg = 1260, and ge = 1800. are these triangles

madreJ [45]

SSS theorem: If two triangles have three pairs of sides in the same ratio, then the triangles are similar.

Write the ratio between the smallest sides, between the greatest sides and between the middle sides and compare the results:

$\dfrac{EF}{AB}=\dfrac{900}{5}=180;$
$\dfrac{EG}{AC}=\dfrac{1800}{10}=180;$
$\dfrac{GF}{CB}=\dfrac{1260}{7}=180.$

This gives you that

$\dfrac{EF}{AB}=\dfrac{EG}{AC}=\dfrac{GF}{CB}=180.$

By SSS theorem triangles ABC and EFG are similar with scale factor 180.

Using the quadratic formula to solve 11x²-4x=1 What are The values of X?

Anvisha [2.4K]

$11x^2 - 4x = 1$
$11x^{2} - 4x - 1 = 1 - 1$
$11x^{2} - 4x - 1 = 0$
$x = \frac{-(-4) \± \sqrt{(-4)^{2} - 4(11)(-1)}}{2(11)}$
$x = \frac{4 \± \sqrt{16 + 44}}{22}$
$x = \frac{4 \± \sqrt{60}}{22}$
$x = \frac{4 \± 2\sqrt{15}}{22}$
$x = \frac{2 \± \sqrt{15}}{11}$
$x = \frac{2 + \sqrt{15}}{11}\ \bold{or}\ x = \frac{2 - \sqrt{15}}{11}$
