Answer:
B and D
Step-by-step explanation:
B= 4(3n-2)
D=12n-8 which equals 4(3n-2)
Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We are given an expression as; 12n – 8.
A. 3n + 4 + 3n + 4 + 4n
= 3n+3n+4n+4+4
=10n+8
B. 11n + 4 + n –12
=11n+n+4-12
=12n-8
C. 6(6n – 2)
=36n-12
D. 4(3n – 2)
=12n-8
E. 4n + 22 – 12 + 8n
=4n+8n+22-12
=12n+10
Therefore, Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.
Step-by-step explanation:
Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.
Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

What is the density at 20oC of 12.0 milliliters of a liquid that has a mass of 4.05 grams?
(if you don't know don't answer it please)
Answer:
Density is defined as mass per unit volume:
density = mass/volume
Density can be calculated using the mathematical formula (expression):
d = m ÷ V
where d = density, m = mass, V = volume
The greater the density, the more mass per unit volume.
The unit of density derived from SI units is kilograms per cubic meter, kg/m3 or kg m-3.
More commonly, densities are given in g/mL (g mL-1) or g/cm3 (g cm-3 or g/cc).
Density is a characteristic property of pure substances so density can help identify a particular pure substance.
Since different substances have different densities, density can also be used to separate one substance from another.
In general, solids are more dense than liquids which are more dense than gases:
density of solid > density of liquid > density of gas
Step-by-step
Answer:
0.338 g/mL
Step-by-step explanation:
Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. This is:
ρ = m/V
ρ = 4.05 g / 12 mL
ρ = 0.3375 g/mL
ρ ≅ 0.338 g/mL

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function
The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.
Now for the first one ]
Lets find Z first
Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.
For the second one this is easier
We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!

You want to measure the length of a ribbon in inches. You only have a centimeter ruler. The length of the ribbon is 15 cm. Is the ribbon longer or shorter than 15 inches? How many inches long is it?
Answer:
Shorter than 15IN, 5.9 or 6 inches
Hope this helps:)
Step-by-step explanation:
The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.
Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,
To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.
To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.
The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:
15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).
So, the ribbon is shorter than 15 inches.
The ribbon is approximately 5.91 inches long.

Answer:
x=2
Step-by-step explanation:
x+(-4) is the same as x-4
First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.
x-4=-2
+4 +4
x= -2+4 or you can see this as 4-2 which is 2
