3(2y + 3) + y

Answers

Answer:

 7y + 9

   

Step-by-step explanation:

Given expression:

     3(2y + 3) + y;

  To solve this problem, apply PEMDAS;

P   = parentheses

E    = exponent

M   = multiplication

D    = division

A     = addition

S      = subtraction

   3(2y + 3) + y;

 Start solving from the parentheses by applying the distributive property;

  6y + 9 + y

  =  7y + 9

how to factor g2 − 32g + 256

Answers

Answer:

Using the snowflake method, you have to find the factors of 256 that add up to get 32.

The result will look like this:

(g-16)(g-16)

Answer:

[tex](g-16)^2[/tex]

Step-by-step explanation:

[tex]g^2-32g + 256[/tex]

To factor it you should remember that

[tex](a-b)^2 = a^2 -2ab+b^2[/tex]

It is easy to seee that

[tex]32 = 2 \cdot 16[/tex]

and

[tex]256 = 16^2[/tex]

Therefore

[tex]g^2-32g + 256 = g^2 - (2\cdot 16)g+ 16^2 = (g-16)^2[/tex]

Step 1: Use the distributive property to remove the parentheses. (2 points)


Step 2: Collect any like terms on both sides of the equation. (2 points)


Step 3: Bring all variable terms to one side of the equation. (Hint: Add x to both sides.) (2 points)

Answers

Answer:

x=-3

Step-by-step explanation:

5(x - 4) + 3x - 9x = 6 - (2x + 5) + 8x

(remove parentheses)

5x-20+3x-9x=6-2x-5+8x

(collect like terms and calculate)

Find the perimeter of the figure.
7 mi
7 mi

Answers

Answer:

28mi

Step-by-step explanation:

The perimeter of a figure is the total length of its outline, so a sum of all its lengths.

In the diagram we are given two of them, both 7, but not the other two.

Luckily these can be easily worked out.

Since this is a square figure (all angles 90-degrees), all parallel sides will be exactly equal in length. This means both of the unknown sides are 7mi long as well. This means the total perimeter is the sum of all four sides, each of which are 7mi.

7+7+7+7 (OR 4x7) = 28 mi

Hope this helped!

Answer:

The perimeter of the figure is 28 mi

Step-by-step explanation:

Perimeter of a Square

Given a square shape of side length A, the perimeter can be found using the expression below:

P = 4*A

Recall the perimeter is the sum of all the side lengths.

Since the figure shows a square with side length A=7 mi, the perimeter is:

P = 4 * 7 mi = 28 mi

The perimeter of the figure is 28 mi

Tabithas living room is rectangle that measures 19 3/4ft by 12ft find the perimeter and the area of the room

Answers

Answer:

237ft²

63.5ft

Step-by-step explanation:

Given parameters:

  Length  = 19[tex]\frac{3}{4}[/tex] ft

   Width  = 12ft

Unknown:

Area of rectangle  = ?

Perimeter of rectangle  = ?

Solution:

Area of rectangle  = length x width

                              = 19[tex]\frac{3}{4}[/tex] x 12

                               = [tex]\frac{79}{4}[/tex] x 12

                               = 79 x 3

                              = 237ft²

Perimeter of rectangle  = 2(length + width)

                                      = 2 (19.75 + 12 )

                                     = 63.5ft

Unable to read, write, or speak, it was thought that Helen would never be able to communicate. "The Story of My Life" describes Helen's education with Anne Sullivan and the unorthodox teaching methods that enabled her to learn how to communicate and thrive.We read and studied out of doors, preferring the sunlit woods to the house. All my early lessons have in them the breath of the woodsthe fine, resinous odour of pine needles, blended with the perfume of wild grapes. Seated in the gracious shade of a wild tulip tree, I learned to think that everything has a lesson and a suggestion. The loveliness of things taught me all their use. Indeed, everything that could hum, or buzz, or sing, or bloom had a part in my educationnoisy-throated frogs, katydids and crickets held in my hand until forgetting their embarrassment, they trilled their reedy note, little downy chickens and wildflowers, the dogwood blossoms, meadow-violets and budding fruit trees. I felt the bursting cotton-bolls and fingered their soft fiber and fuzzy seeds; I felt the low soughing of the wind through the cornstalks, the silky rustling of the long leaves, and the indignant snort of my pony, as we caught him in the pasture and put the bit in his mouthah me! how well I remember the spicy, clovery smell of his breath!Sometimes I rose at dawn and stole into the garden while the heavy dew lay on the grass and flowers. Few know what joy it is to feel the roses pressing softly into the hand, or the beautiful motion of the lilies as they sway in the morning breeze. Sometimes I caught an insect in the flower I was plucking, and I felt the faint noise of a pair of wings rubbed together in a sudden terror, as the little creature became aware of a pressure from without.Another favourite haunt of mine was the orchard, where the fruit ripened early in July. The large, downy peaches would reach themselves into my hand, and as the joyous breezes flew about the trees the apples tumbled at my feet. Oh, the delight with which I gathered up the fruit in my pinafore, pressed my face against the smooth cheeks of the apples, still warm from the sun, and skipped back to the house!Our favourite walk was to Keller's Landing, an old tumbledown lumber-wharf on the Tennessee River, used during the Civil War to land soldiers. There we spent many happy hours and played at learning geography. I built dams of pebbles, made islands and lakes, and dug river-beds, all for fun, and never dreamed that I was learning a lesson. I listened with increasing wonder to Miss Sullivan's descriptions of the great round world with its burning mountains, buried cities, moving rivers of ice, and many other things as strange. She made raised maps in clay, so that I could feel the mountain ridges and valleys, and follow with my fingers the devious course of rivers. I liked this, too; but the division of the earth into zones and poles confused and teased my mind. The illustrative strings and the orange stick representing the poles seemed so real that even to this day the mere mention of temperate zone suggests a series of twine circles; and I believe that if any one should set about it he could convince me that white bears actually climb the North Pole.Part AWhat does Helen Keller's word choice in her description of her lessons with her teacher, Anne Sullivan, reveal about Keller? A. Her lessons are easier for her when she learns them outdoors. B.She feels connected to the natural world despite her lack of sight. C.The natural world holds many mysteries for her that she wishes to solve. D. She no longer misses her sense of sight when she is outside.Question 2Part BHow does the word choice in paragraph 1 help to develop the idea in Part A? A. Keller includes comparisons of her education to things that occur naturally in the wild. B. Keller includes descriptions of natural things that she can touch and smell. C. Keller includes the phrase breath of the woods to show that the natural world is living. D.Keller includes the sentence The loveliness of things taught me all their use to show that nature is a teacher. On a farm, the farmer decides to give pizza to her 15 ducks as a special treat.
