The 2 formulas of rectangular prism are Volume = Length x Width x Height cubic units and Surface Area of a rectangular prism = 2 (lh +wh + lw ) Square units.
An item with three dimensions is a rectangular prism. It will therefore have its own volume and surface area. We need to know the dimensions of a prism's sides or edges in order to compute its volume and surface area. Let l, w, and h represent the dimensions of the rectangular prism. Below are the supplied formulas.

factorise completely:
1. 3xy - x
2. 4a² - 9
Answer:
x(3y - 1) and (2a - 3)(2a + 3)
Step-by-step explanation:
(1)
3xy - x ← factor out x from each term
= x(3y - 1)
(2)
4a² - 9 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4a² - 9
= (2a)² - 3²
= (2a - 3)(2a + 3)

Box 1
x - y = 4
x - 0 = 4
x = 4
Box 2
x = 4
y = 0
(x, y) => (4, 0)
Box 3
x - y = 4
-1 - y = 4
-y = 4 + 1
y = -5
Box 4
x = 0
y = -4
(x, y) => (0, -4)
help! i just need the answers. maybe some explanations would be good too :)
For Number one: -xy + 2x = 20, x = 5
To solve this, all we need to do is plugin 5 for every place we have x. So...
- (5)y + 2(5) = 20
-5y + 10 = 20
-5y = 10
y = -2
For number two: 4x - 3y - 10 = 1, x = -1
To solve this, we need to plugin -1 for all of the x variables. So...
4 (-1) - 3y - 10 = 1
-4 - 3y - 10 = 1
-14 - 3y = 1
-3y = 15
y = -5
For number three: 5x + 7y = -1, x = 4
We need to plugin -4 for all of the x variables. So...
5 (4) + 7y = -1
20 + 7y = -1
7y = -21
y = -3
For number four: x = 6 + xy, x = -3
Same as the other ones, just plugin -3 for all of the x variables. So...
-3 = 6 + (-3)y
-3 = 6 - 3y
-9 = -3y
3 = y
I hope this helps :)

In the form of a paragraph, use complete sentences to describe some of your observations that helped you to conclude who researched textbook prices. Use specific examples from the data, histograms and box and whisker plots.
Answer:
It was most likely Tyler who researched it as his range of books is much larger than that of Felix.
Step-by-step explanation:
From the bar graph to the box and whisker plot, the right is always the one with more variety just as in the first plot that was shown.

What is a Scatter Plot?Dots are used in a scatter plot to show the values of two different numerical variables. Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.
The closer the data points come to forming a straight line when plotted, the higher the correlation between the two variables, or the stronger the relationship. If the data points make a straight line going from near the origin out to high y-values, the variables are said to have a positive correlation.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
Given data ,
Let the scatter plot represents the funds raised by a TV station since its first year of operations
Let the number of years be represented as x
Let the contribution be represented as y
where the values of x and y are
x = { 1 , 3 , 5 , 8 , 11 , 14 }
y = { 70000 , 150000 , 190000 , 230000 , 270000 , 290000 }
The scatter plot is graphed and the linear regression equation is
y = 15901.6x + 88688.5
Hence , the scatter plot for the contribution for x years is plotted

4. Consider the circle to the right.
Determine m∠KNY.
Show all steps to be marked brainliest. I will give brainliest as soon as I can.
Answer:
The measure of m∠KNY is;
(D) 105°
Step-by-step explanation:
From the diagram, we have;
The given angle at the circumference = The The angle the arcs makes at the center of the circle
From circle, theorem, angle subtended at the center = Twice the angle subtended at the circumference
Therefore;
Angle ∠D and angle ∠Y = 90°/2 = 45°
Angle ∠O and angle ∠K = 60°/2 = 30°
From angle summation theorem, we have;
m∠KNY + ∠K + ∠Y = 180° (The sum of the interion angles in ΔYNK
∴ m∠KNY = 180° - (∠K + ∠Y)
Plugging in the known values of ∠K and ∠Y gives;
m∠KNY = 180° - (30° + 45°) = 105°
m∠KNY = 105°.

Answer:
x = 12 cm
Step-by-step explanation:
Based on the tangent and secant theorem,
8² = 4(4 + x)
Solve for x
64 = 16 + 4x
Subtract 16 from both sides
64 - 16 = 4x
48 = 4x
Divide both sides by 4
48/4 = 4x/4
12 = x
x = 12
