The area of the triangle GHJ is 48 square units.
The area of a triangle can be found using the formula:
Area = (1/2) * base * height.
In this question, we are given that triangle GHJ has a base of 12 units and a height of 8 units. To find the area of the triangle, we simply substitute these values into the formula and solve.
Area = (1/2) * 12 * 8 = 48 square units
To be more specific, first, we multiply the base and height together to get 12*8 = 96. Then we divide 96 by 2 to get 48. Therefore, the area of triangle GHJ is 48 square units.
It's important to note that the base and height of a triangle must be perpendicular to each other in order for the formula to be accurate. Also, the unit of measurement used for the base and height must be consistent, otherwise, the area calculated will not be correct.

The expressions that could represent the amount Bo would pay for the game: 0.82B and B - 0.18B
The correct options are: option (a) and option (e)
Given that the board game costs B dollars.
And the price is reduced by 18%.
So, the discount percentage is 18%
i.e., the price is reduced by 0.18
To find out discount amount on the board game, we multiply cost of the board game by discount percentage.
So, we get an expression for the discount amount = 0.18B
Now we calculate total price of the board game.
Subtract the discount amount from original price B
So, we get an expression for the total price of the board game.
B - 0.18B
As the discount percentage is 18%, then the original percentage of pay is about 100 - 18 = 82%

100 points + Brainliest Let C represents the cost in dollars and R represents the revenue in dollars. What is the break-even point? Use a table to help if necessary.
C=36x+200
R=76x
Break-even point: ([],[])
Answer:
The break even point is 380.
Step-by-step explanation:
36x + 200 = 76x
200 = 76x - 36x
200 = 40x
200/40 = x
5 = x
C = 36(5) + 200 R = 76(5)
C = 180 + 200 R = 380
C = 380
Answer:
The breakeven point is 5 units
Step-by-step explanation:
C is the cost ($) and R is the revenue ($).
We are told that :
R=76x
C=36x+200
Profit would be the Revenue minus the Cost:
Profit = R - C
The "breakeven point" is the situation in which there is neither a profit nor a loss. That means that the total profit equals the total cost for x units. We want to find the value of x that would result in no profit or loss: Profit = 0.
0 = R-C
====
Profit = 76x - (36x+200)
Profit = 40x - 200
0 = 40x - 200 [The Breakeven Point]
-40x = -200
x = 5 units
5 units results in 76*5 or $380 in revenue.
5 units results in a cost of 36*(5)+200 or $380 in costs.
The result is breakeven (Profit = $390 - $380) of $0.00

What is n to the power of 6?
n to the power of 6, also written as n⁶, is a mathematical operation that raises the number n to the sixth power. This means that n is multiplied by itself six times.
For example, if n = 2, then n⁶ = 2 × 2 × 2 × 2 × 2 × 2 = 64.
Exponentiation is a mathematical operation that is used to represent repeated multiplication. The number that is being multiplied is called the base, and the number that represents how many times the base is being multiplied is called the exponent. In the case of n⁶, the base is n and the exponent is 6.
In general, when raising a number to a power, the result is the product of that number multiplied by itself the number of times represented by the exponent. For example, n³ = n × n × n and n⁴ = n × n × n × n.
In addition to being a mathematical operation, exponentiation also has practical applications in fields such as computer science, engineering, and physics.

Repeat the process to get zero or arrive at a remainder.
We shall rearrange 16 - 8x - 7x² + 2x³ to become 2x³ - 7x² - 8x + 16 and then divide by x - 4 as follows;
2x³ divided by x equals 2x²
x - 4 multiplied by 2x² equals 2x³ - 8x²
subtract 2x³ - 8x² from 2x³ - 7x² - 8x + 16 will give x² - 8x
x² divided by x equals x
x - 4 multiplied by x equals x² - 4x
subtract x² - 4x from x² - 8x will give us -4x + 16
