Answer:

3x, 2x + 5, and x - 3

Step-by-step explanation:

Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.

Our equation is:

6x³ - 3x² - 45x

First, we can factor out an x:

x (6x² - 3x - 45)

From here, we can see that by factoring out a 3:

3x (2x² - x - 15)

Now, after completing the square and factoring:

3x (2x + 5) (x - 3)

These are our three expressions.

PLEASE HELP NOW I ONLY NEED TO KNOW NUMBER 5. 25 POINTS!!!

Anika [276]

If Point C and D are equidistant from point A, it means that AC and AD are of the same length. AC = AD

AC = AD (S) (<span>Points C and D are equidistant from point A)
</span>AE = AE (S) (The two triangle shared the same side)
∠CAE = ∠EAD (A) (This angle is between the two sides that we just proved to be equal)

By SAS,
ΔEAD ≡ ΔEAC

Given g ( x ) = 2 x + 3 , solve for x when g(x)=3.

padilas [110]

Answer:

x = 0

Step by step explanation:

g ( x ) = 2x + 3

If x = 0,

g ( 0 ) = 2 (0) + 3

or, g ( 0 ) = 3

Find the value of x y and z below !

ehidna [41]

Answer:

$x=67, y=121, z=65$

Step-by-step explanation:

One property of parallelogram is that opposite angles have the same measure, so we can write down:

$(y-9)=112\\y=121$

Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:

$(z+3)+112=180\\(x+1)+112=180$

Solve the equations:

$(z+3)+112=180\\z+115=180\\z=65\\(x+1)+112=180\\x+113=180\\x=67$

To check, add up all 4 angles and check if they sum up to 360 degrees:

$x=67, y=121, z=65\\(y-9)+(x+1)+(z+3)+112=360\\(121-9)+(67+1)+(65+3)+112=360\\112+68+68+112=360\\360=360$

And please ignore the fact that I cannot insert the degree sign :(

The numbers of calories per serving for various snakes foods are listed below.

Elanso [62]

Answer:

B. 108 calories

Step-by-step explanation:

The mean number of a data set is

$\text{Mean}=\dfrac{\text{The sum of all calories in products}}{\text{The number of products}}$

Corn chips: 230 calories

Popcorn: 25 calories

Potato chips: 115 calories

Pretzels: 62 calories

Thus,

The sum of all calories $=230+25+115+62=432$

The number of productrs = 4

The mean number of calories $=\dfrac{432}{4}=108$
