What is a polynomial?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involving only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. x² + 4x + 7 is an illustration of a polynomial with a single indeterminate x.
When exponents, constants, and variables are combined using mathematical operations like addition, subtraction, multiplication, and division, the result is a polynomial.
In conclusion, the correct option is columns.

Lines c and d are perpendicular. The equation of line c is y=−12x+1. What is the equation of line d?
Answer:
y=1/12x+b
Step-by-step explanation:
To find a perpendicular line, you need to find the negative reciprocal of the gradient in this case its -12x, the negative reciprocal of this is 1/12x we don't know what coordinates this passes through so we just write y=1/12x+b

An unopened cereal box contains `15/28` cubic foot of cereal. If the box is full, and the length and height of the box are `5/7` and `1(1)/(2)` feet, respectively, what is the width of the box? A. `1/2` foot B. `1/7` foot C. `3/5` foot D. `4/7` foot
Answer:
A. `1/2` foot
Step-by-step explanation:
The computation of the width of the box is shown below:
15 ÷ 28 = (5 ÷ 7)(1 1 ÷ 2)(width)
15 ÷ 28 = (5 ÷ 7)(3 ÷ 2)width
15 ÷ 28 = (15 ÷ 14)width
(15 ÷ 28) ÷ (15 ÷ 14) = width
(15 ÷ 28) × (14 ÷ 15) = width
w = 14 ÷ 28
= 1 ÷ 2 ft

Answer:
y=x+10
Step-by-step explanation:
it's a guess. it goes up 1 over 1 so the "m" in y=mx+b has to be 1. so x stands alone. the line looks like it begins at 10 so the b will equal 10
Answer:
y = 5x + 10
Step-by-step explanation:
Line is passing through the points (2, 20) & (4, 30)
Slope of line (m) = (30 - 20)/ (4 - 2) = 10/2 = 5
y - 20 = 5(x - 2)
y = 5x - 10 + 20
y = 5x + 10

Step-by-step explanation:
1. Make a fraction with the total number of cards at the bottom (60) and all the cards that are not green (aka yellow and blue) on top (42). Then simplify the fraction 42/60 by dividing both terms by 6 to get 7/10
2. For this one, first find how many students out of the first 80 liked basketball by subtracting the 60 students who liked other sports from 80. This gives you 20. Now you know that 20/80 students like basketball. Now simplify the fraction to get 1/4. Then find 1/4 of 100, because we know that 1/4 of students like basketball. 1/4 of 100 is 25.
3. This problem is exactly the same as number 1, except instead of adding all the other colors and putting them as a fraction over the total, just put the number of pink shirts over the total number of shirts to get 3/12. Then simplify it to 1/4, and that's your answer.
4. This is also similar to problems 1 and 3. Just put the number of heads coin tosses over the total and simplify it.
5. This one is very similar to all the problems so far. I will let you do this one on your own. Remember: The number of cases (rolls or colors or sports or cards etc.) that you want to find the probability for goes on top, and the total number of those things goes on the bottom. The bigger the fraction, the greater probability there is.
Note: Please only ask one question at a time on here instead of 5 at once. Since these problems are so similar, chances are, you could have figured them out on your own with a little help on one of them. You are more likely to get a quick answer if the answerer doesn't have to do as much work.

Answer:
The equation is:
y = -15*x + 1200
and:
a = 120
b = 70
c = -1500
Step-by-step explanation:
This seems to be a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that our line passes through the points (60, 300) and (20, 900)
Then the slope of this line is:
a = (900 - 300)/(20 - 60) = 600/(-40) = -15
Then this line is something like:
y = -15*x + b
To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.
Replacing these values in the above equation we get:
300 = -15*60 + b
300 + 15*60 = b = 1200
Then:
y = -15*x + 1200.
Now that we have this equation, we can complete the table.
a is the value for y, when x = 72
Then we can replace x by 72 in the above equation:
a = -15*72 + 1200 = 120
a = 120
b is the value of x when y = 150, then we need to replace y by 150
150 = -15*b + 1200
150 - 1200 = -15*b
(150 - 1200)/-15 = b = 70
then:
b = 70
c is the value of y when x = 180, then we need to replace x by 180.
c = -15*180 + 1200
c = -1500

Determine the length of the longest piece of timber which could be stored in a rectangular shed 6cm by 5cm by 2m high
Answer:
6 90u7 jhi
Step-by-step explanation:
Answer:
200.2
Step-by-step explanation:
I would hate to own such a shed. It's not very big.
2 meters = 2 * 100 cm = 200 cm
The diagonal of the floor is the diagonal of 6cm by 5cm. Using a^2 + b^2 = c^2
5^2 + 6^2 = 25 + 36 = 61
The square root of 61 is 7.81 cm
Now the diagonal of the floor diagonal and the height
a^2 + h^2 = board^2
61 + 200^2 = board^2
61 + 40000 = board^2
40061 = board^2
sqrt(board^2) = sqrt(40061)
board = 200.2cm long.
