Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm
==============================================
Work Shown:
L = 2 = lengthW = 6 = widthH = 9 = heightThe order of length, width and height doesn't matter
SA = surface area of rectangular prism
SA = 2*(LW + LH + WH)
SA = 2*(2*6 + 2*9 + 6*9)
SA = 2*(12 + 18 + 54)
SA = 2*(30+54)
SA = 2*(84)
SA = 168 square cm

pls help me solve pls show how you got the answer
Step-by-step explanation:
the answer is number a 88 CM square
hey, if the volume is 8cm^3, each side will be 2 cm, why? because 8√3 equals 2. or 8=2×2×2.
so each side equals 2.
to calculate the surface area, we need to calculate one square's area and multiples it by the number of the surfaces.
to calculate a square's area: 2×2=4
so each square has the surface of 4cm^2
now we count to see how many squares do we have.
we've got 22 surfaces.
so 22×4=88cm^2
then option C is the answer
my mother tongue isn't English so my apologies if I couldn't explain well

The required value of tan(7π/12) = √[(2+√3)/(2-√3)].
To find the exact value of tan(7π/12).
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
[tex]tanx =\sqrt{ \frac{1 -cos2x}{1 + cos2x} }[/tex]
tan(7π/12) = √ [ (1 - cos2(7π/12) ) / (1 + cos2(7π/12) ]
= √ [ (1 - cos(7π/6) ) / (1 + cos(7π/6) ]
= √ [ (1 - cos(π + π/6) ) / (1 + cos(π + π/6) ]
Since cos(π + x) = -cosx
= √ [ (1 + cos(π/6) ) / (1 - cos(π/6) ]
Here, cos( π/6 ) = √3/2
= √ [ (1 + √3/2 ) / (1 - √3/2 ]
= √ [ (2 + √3)/2 / (2- √3)/2 ]
= √ [ (2 + √3) / (2- √3) ]
Thus, the required value of tan (7π/12) = √ [ (2+√3)/(2-√3) ].

What is a function?
A function of an expression, rule, or law that defines the relationship between one variable (independent variable) and another (dependent variable) in mathematics. Functions are ubiquitous in mathematics and are essential for the formulation of physical relationships in the natural sciences.
Functions can be defined as a set of ordered pairs. Example: {(2,4), (3,5), (7, 3)} is a function that says. "2 is associated with 4," "3 is associated with 5," and "7 is associated with 3." Also note that the domain is {2,3,7} (input value). A
function is defined as a relationship between a set of inputs, each with an output. Simply put, a function is a relationship between inputs, where each input is associated with one output. Each function has a domain and a codomain or scope.

The blueprint of a deck has a scale of 2 centimeters equals 9 feet. The scale drawing is shown below
I have part A I need help with b
Part B
Decking costs $1.75 per square foot. How much will it cost to build the deck?
Complete question is;
The blueprint of a deck has a scale of 2 centimeters equals 9 feet.
A) What are the actual lengths of the sides of the deck?
B) Decking costs $1.75 per square foot. How much will it cost to build the deck?
Answer:
A) actual lengths are;
27 ft, 36 ft and 45 ft
B) cost of entire deck = $850.5
Step-by-step explanation:
A) From the attached image, we see that the sides of the triangle deck are;
8cm, 10cm and 6 cm
Now, we know that 2cm represents 9 ft.
Thus;
8cm will be; 8 × 9/2 = 36 ft
10 cm will be; 10 × 9/2 = 45 ft
6 cm will be; 6 × 9/2 = 27 ft
Thus, actual lengths are;
27 ft, 36 ft and 45 ft
B) Area of deck is Area of triangle = ½ × base × height.
In this diagram, base = 6 cm = 27ft
Height = 8 cm = 36 ft
Thus;
Area of deck = ½ × 27 × 36
Area of deck = 486 ft²
We are told that the Decking costs $1.75 per ft²
Thus;
Cost of entire deck = 1.75 × 486 = $850.5

Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?
5n – 300 = 1,500
5n + 300 = 1,500
5n – 200 + 100n = 1,500
5n – 100 – 200n = 1,500
Answer:
The first one, A
Step-by-step explanation:
DJ costs $300 in total.
For every student there is $5.
We want a profit of 1,500, so the total money earned from students attending subtracted by the costs of the DJ should be 1,500.
5n - 300 = 1,500
For the second one, it'll be the DJ giving you $300.
The last Two answers has an n where it's supposed to be money when n represents each student.
