Answers
A and B
The equivalent values of the expression A = 4 + w + 12w are B = 4 + 13w and C = 2 ( 2 + 6w ) + w
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To find the expressions that are equivalent to 4 + w + 12w, we need to simplify the expression and see which of the given expressions have the same result.
4 + w + 12w = 4 + 13w
So, the equivalent expressions are (a) 4 + 13w and (c) 2(2 + 6w) + w.
Let's check the other options:
(b) 13w² + 4: This is not equivalent, as it involves squaring the w term.
(d) 16 + 2w: This is not equivalent, as it involves adding a constant term.
(e) 2(2 + 6w²): This is not equivalent, as it involves squaring the 6w term.
Hence , the two expressions that are equivalent to 4 + w + 12w are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Answer: 55 m²

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answers
She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:
2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276
So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.
To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.
- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.
So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.
Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

However, I haven't done these kinds of questions in a long time, therefore I could be wrong.
On a snowy day 85% of the students of Wilson high school were present., There were 672 students enrolled at Wilson high school.
To find out how many students were enrolled at Wilson high school, we can use the information given in the question. We are told that 85% of the students were present on a snowy day, and that 572 students were present. To find the total number of students enrolled, we can set up a proportion: Present students / Total students = Percentage present / 100 Let's plug in the values we know: 572 / Total students = 85 / 100 To solve for the total number of students, we can cross-multiply and solve for Total students: 572 * 100 = Total students * 85 57200 = Total students * 85 Dividing both sides by 85: 57200 / 85 = Total students Total students = 672 Therefore, there were 672 students enrolled at Wilson high school.

How did you decide where to place your line of best fit? Describe your reasoning.

Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

you bought a magazine for $5 and four erasers. you spent a total of $25. how much did the eraser cost?
Answers
Answer:
1 eraser = $54 erasers = $20Step-by-step explanation:
Given that,
→ Magazine = $5
→ Total cost = $25
→ 1 eraser = x
The equation will be,
→ 4x + 5 = 25
Now the value of x will be,
→ 4x + 5 = 25
→ 4x = 25 - 5
→ x = 20/4
→ [ x = $5 ]
Hence, value of x is $5.
Total= $25- $5 magazine leaves you with $20. You bought 4 erasers so you do 20/4 which is $5

Plot and connect the points A (2, -2), B (-4, -4), C (-4, -1), D (-2, 3), E (1, 3), F (2, 5), and find the length of BC.
Answers
Answer:
BC = 3 units
Step-by-step explanation:
Given points:
A = (2, -2)B = (-4, -4)C = (-4, -1)D = (-2, 3)E = (1, 3)F = (2, 5)Plot the points on the coordinate plane (x, y) and connect them in alphabetical order with straight lines (see attached).
From visual inspection of the drawn polygon, we can see that the length of BC is 3 units.
It is fairly simple to calculate the length of BC without plotting the points.
As points B and C have the same x-value, this means that the distance between them is simply the difference between their y-values.
⇒ distance = |-4 - (-1)| = |-3| = 3 units
Distance

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.
