The value of g (2w) is,
g (2w) = 4w² + 4w + 1
What is substitution method?
To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.
The given function is;
g(x) = x² - 2x + 1
Now, The value of g (2w) is calculated as;
g(x) = x² - 2x + 1
Put x = 2w in above equation,
g (2w) = (2w)² + 2 (2w) + 1
g (2w) = 4w² + 4w + 1
Hence, The value of g (2w) is ( 4w² + 4w + 1 ).
So, The value of g (2w) is,
⇒ g (2w) = 4w² + 4w + 1

Please older brother is 4 3/4 feet tall lien is 1/3 foot shorter than his brother how old how tall is Leon
Answer: Leon is 53/12 feet tall (4 5/12)
Step-by-step explanation:
Hi, to answer this question we have to subtract the height difference (1/3 ) to the Older brother's height. (4 3/4).
Mathematically speaking:
4 3/4 -1/3 = (4x4+3)/4 -1/3 = 19/4 -1/3 = 57/12-4/12 = 53/12 feet
Leon is 53/12 feet tall (4 5/12)

Frank needs to memorize words on a vocabulary list for Latin class. He has memorized
6
of the words, which is two-thirds of the list. How many words are on the list?
Frank has memorized 6 words which is two-thirds of his vocabulary list, so by dividing 6 by 2/3, we find out that the total number of words on the list is 9.
Frank has memorized 6 words on his Latin vocabulary list, which is two-thirds of the total number of words. To find out the total number of words on the list, we can set up a proportion where 6 words corresponds to 2/3. Therefore, we need to find a number that, when multiplied by 3/2 or 1.5, gives us 6.
We can set up the equation like this: 2/3 * total words = 6 words. To find the total words, we divide 6 by 2/3:
total words = 6 ÷ (2/3)
total words = 6 * 3/2
total words = 9
So, the vocabulary list has a total of 9 words.
It takes 52 minutes for 5 people to paint 5 walls. How many minutes does it take 20 people to paint 20 walls?
Answer:52 min
Step-by-step explanation:
Given
5 people paint 5 walls in 52 minutes
Now if 1 person paints the 5 walls then time required will be 5 times more
1 Person paint 5 walls in [tex]52\times 5[/tex]
For 20 walls person has to do 4 times the previous walls
1 person paints 20 walls in [tex]52\times 5\times 4[/tex]
For 20 People time required will be 20 times less
i.e.
[tex]\frac{52\times 5\times 4}{20}=52 mins[/tex]
find the slope of the line through P(5,7) and Q( -1 + 7)
Final answer:
The slope of the line through points P(5,7) and Q(-1,7) is calculated to be 0, indicating a horizontal line.
Explanation:
To find the slope of the line through points P(5,7) and Q(-1,7), we can use the formula for the slope of a line through two points: slope (m) = (y2 - y1) / (x2 - x1). In this case, the coordinates for P are (x1, y1) = (5, 7) and the coordinates for Q are (x2, y2) = (-1, 7).
Plugging these values into the slope formula, we get:
m = (7 - 7) / (-1 - 5)
m = 0 / (-6)
m = 0
So the slope of the line is 0, which means that the line is horizontal.

1. A room is in the shape of a rectangle. The width of the room is 2 feet longer than two thirds the length. If the room is 33 feet long, what is the area?
To calculate the area of the rectangular room with a length of 33 feet and width that is 2 feet longer than two thirds of its length, we first find the width to be 24 feet and then multiply it with the length to get the area of 792 square feet.
Calculating the Area of a Rectangle
The question involves finding the area of a rectangular room given the length and a relationship between the length and width. The room is 33 feet long and the width is stated to be 2 feet longer than two thirds of the length. First, we determine the width by using the length to find two thirds of it and then adding 2 feet:

The set which is the subset of every set is:
Empty set or null set.
Step-by-step explanation:Set--
A set is a well defined collection of the distinct objects.
The number of objects in the set is the cardinality of the set.
The set whose cardinality is zero is known as the empty set or the null set.
i.e. it is the set which is having zero element i.e. no element.
Such a set is unique.
Also, the null set or the empty set is the subset of every set.

find the next 3 terms of the following sequence 22 21 18 13 6
The next 3 terms of the sequence 22, 21, 18, 13, 6 are 2, -3, and -8.
Explanation:The next 3 terms of the sequence 22, 21, 18, 13, and 6 can be found by analyzing the pattern in the sequence. The difference between each term is decreasing by 1 each time. So, the next difference would be 5 - 1 = 4. Subtracting 4 from 6 gives us 2. Therefore, the next term in the sequence is 2. Repeating this process, we can find the following terms: 2, -3, and -8.

If a bookshelf is 28 1/8 inches long,how many 1 7/8 inch thick books will it hold?
Answer: Bookshelf can hold 15 books.
Step-by-step explanation:
Given : The length of the book shelf = [tex]28\dfrac{1}{8}[/tex] inches
In improper fraction , [tex]28\dfrac{1}{8}=\dfrac{8(28)+1}{8}=\dfrac{225}{8}[/tex]
i.e. Length of the book shelf = [tex]\dfrac{225}{8}[/tex] inches
Similarly, Thickness of a book = [tex]1\dfrac{7}{8}=\dfrac{8(1)+7}{8}=\dfrac{15}{8}[/tex] inches
Now, the number of books the shelf can hold = Length of the bookshelf ÷Thickness of a book
[tex]=\dfrac{225}{8}\div\dfrac{15}{8}\\\\=\dfrac{225}{8}\times\dfrac{8}{15} \\\\=\dfrac{225}{15}=15[/tex]
Hence, the bookshelf can hold 15 books.
