Answer:

B

Step-by-step explanation:

f(x) - g(x)

= 2x² - 4x - 3 - (x - 4)(x + 4) ← expand using FOIL

= 2x² - 4x - 3 - (x² - 16) ← distribute by - 1

= 2x² - 4x - 3 - x² + 16 ← collect like terms

= x² - 4x + 13 → B

Solution :

In the figure, the box plot represents the lengths of the songs of the two digital music players that is in minutes.

From the figure, we can see that for the music player Y, the interquartile range of the data is small.

And the interquartile range of data is more for the music player X.

So, we can conclude that the interquartile range of data is greater for Music player X than the interquartile range data of music player Y.

Answer:

Step-by-step explanation:

Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.

  3 = x² +2x

Now, add the square of half the x-coefficient.

  3 +1 = x² +2x +1

  (x +1)² = 4 . . . . . . . . write as a square in the desired form

__

To solve, take the square root, and add the opposite of the left-side constant.

  x +1 = ±2

  x = -1 ±2 . . . . . . matches choice (D)

Answer:

-20 feet

Step-by-step explanation:

change in depth = number of feet below the surface + number of depth on the surface

Because the submarine is below surface, a value of -30 would be given

-30 + 10 = -20 feet

Answer:

5^2 =25/ 2.5x 6 =12

Step-by-step explanation:

Answer: x = 15.035677095729 approximately

Round this however you need to.

=================================================

Explanation:

I'm assuming you want to find the value of x, which your diagram is showing to be the length of segment QR.

If so, then we'll need to find the measure of angle Q first. Using the law of sines, we get the following:

sin(Q)/q = sin(R)/r

sin(Q)/PR = sin(R)/PQ

sin(Q)/13 = sin(85)/19

sin(Q) = 13*sin(85)/19

sin(Q) = 0.6816068987

Q = arcsin(0.6816068987) ... or ... Q = 180-arcsin(0.6816068987)

Q = 42.9693397461 ... or ... Q = 137.0306602539

These values are approximate.

----------------

Now if Q = 42.9693397461 approximately, then angle P is

P = 180-Q-R

P = 180-42.9693397461-85

P = 52.0306602539

Similarly, if Q = 137.0306602539 approximately, then,

P = 180-Q-R

P = 180-137.0306602539-85

P = -42.0306602539

A negative angle is not possible, so we'll ignore Q = 137.0306602539

----------------

The only possible value of angle P is approximately P = 52.0306602539

Let's apply the law of sines again to find side p, aka segment QR

sin(P)/p = sin(R)/r

sin(P)/QR = sin(R)/PQ

sin(52.0306602539)/x = sin(85)/19

19*sin(52.0306602539) = x*sin(85)

19*sin(52.0306602539)/sin(85) = x

x = 15.035677095729

This value is approximate.

Round this value however you need to.

What I would do is draw it out in a net. Then find the area of each area of the net. After you calculate the areas, you'll get these numbers: 18, 18, 12, 12, 6, and 6. Then add them all together.

The final answer is 72 square centimeters.

Answer:

The answer to this question is 68

Answer:

m∡ABD = 68°

Step-by-step explanation:

let x = m∡ABD

44 + 2x = 180

2x = 136

x = 68

Answer: 60 degrees

if angle dgc equals 90 (the little square means right angle which is 90 degrees) that means dga equals 90 too (because they are supplementary angles which equal 180 together)

90 - 30 = 60 (minus 30 bc 30 needs to be subtracted in order to find angle dge)

vertical angles are equivalent so x = 60

:)

Answer:

60

Step-by-step explanation:

because the unmarked angle is vertical pairs with the 90º, we know it is 90º

xº=180º-30º-90º

=90º-30º

=60º

Answer:

Tuvieron que comprar 3.73 kg.

Step-by-step explanation:

Para obtener la  respuesta, tienes que encontrar a cuántos kilogramos equivalen 8.3 libras de dulces y para esto puedes utilizar una regla de tres teniendo en cuenta que 1 libra es igual a 0.45 kilogramos:

    1 libra    → 0.45 kilogramos

8.3 libras   →             x

x=(8.3*0.45)/1=3.73 kg

De acuerdo a esto, la respuesta es que tuvieron que comprar 3.73 kg.

The tree that shows the correct combination of one flavor of ice cream and one topping is the the first tree.

A tree diagram is a tool in the fields of general mathematics, probability, and statistics that helps calculate the number of possible outcomes of an event or problem, and to cite those potential outcomes in an organized way.

Tree diagrams, also known as probability trees or decision trees, are quite versatile and may be useful in many fields, including finance.

A tree diagram lets a user start at a single point and make mutually exclusive decisions or experience mutually exclusive events to follow a path down the branches of the tree. Using a tree diagram is simple once you assign the appropriate values to each node.

From the question, and the definition it is clear that vanilla splits into fudge and caramel and chocolate to sprinkles.

Hence A is the correct option.
