help plss, ill give brainliest<33.
which expression is not equivalent to the other three?
a) 2x + 2+ 2x + 3x – 8
b) 4 + 7x – 2
c) –2 + 5x + 2x – 4
d) 8x – x – 6
4+7x-2
========================================================
Explanation:
Combine the like terms in choice A to find that:
2x+2x+3x = 7x2-8 = -6Therefore, choice A simplifies to 7x-6.
Choice B on the other hand simplifies to 7x+2 since 4-2 = 2.
The expressions 7x-6 and 7x+2 don't match up, which means the answer is either choice A or choice B.
--------------
Let's simplify choice C.
5x+2x = 7x-2-4 = -6Choice C simplifies to 7x-6 which matches with choice A. In other words, choices A and C are equivalent expressions. We can rule out choice A and go with choice B as the final answer.
For the sake of completeness, let's simplify choice D
8x-x-6 = 7x-6
This shows choice D matches with A and C.
--------------
Summary:
Choice A simplifies to 7x-6Choice B simplifies to 7x+2Choice C simplifies to 7x-6Choice D simplifies to 7x-6Answer:
B

Step-by-step explanation: Surface area of triangular prism = 2A + PH.
Lateral surface of a triangular prism = Length × (a + b + c)
i hope it helps u :-)
Answer:
225 and 243.4
Step-by-step explanation:
Area of triangle = bh/2
A = 4*4.6/2
A = 9.2 cm sq
A of 2 triangles = 9.2*2 = 18.4 cm sq
Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq
A of 3 rectangles = 75*3 = 225 cm sq
Now, LSA = 225 cm sq. (excluding the triangles)
TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Which proportion would you use to solve the following problem?
A map has a scale of 1 cm : 5 km. Determine how far apart two cities are if they are 8 cm apart on the map.
A. 1/5 = 8/x
B. 1/x = 5/80
C. 1/5 = 80/x
D. 1/x = 8/5
i need HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
No, they are not in proportion
Step-by-step explanation:
As when we cross-multiply 2/3 and 7/10, we get 20 = 21
When we cross-multiply 1 and 3/5, we get 5 = 3
When we cross-multiply 4/3 and 1/2, we get 8 = 3
20=21 ≠ 5=3 ≠ 8=3
∴ Hence, they are not in proportion.

He purchases a total of 150 containers of popcorn to sell. After he sells 15 containers, he will make a total profit, after his upfront costs, of $5.50. Cassidy’s profit, after upfront costs, can be modeled by a linear function in the form y=mx+b.
Question 1
Part A
What is the slope of the line that models the function?
Enter the correct answer in the box.
Answer: 208.00
Step-by-step explanation:If Cassidy sells all of the popcorn, his profit would be equal to $208.00.
What is the slope-intercept form?
Mathematically, the slope-intercept form of a line can be modeled by using this linear function:
y = mx + b
Where:
m represents the slope.
x and y are the points.
b represents the y-intercept.
How to determine Cassidy’s profit?
In order to determine Cassidy’s profit, we would have to calculate the cost of the containers of popcorn by using this mathematical expression:
Note: the price tag for a container of popcorn is one dollar and fifty cents.
Cost of containers = revenue - total profit
Cost of containers = 1.50(15) - 5.50
Cost of containers = 22.5 - 5.50
Cost of containers = $17.00
Therefore, the linear function which models Cassidy’s profit is given by:
y = 1.50x - 17
If Cassidy sells all of the popcorn, his profit is given by:
Cassidy’s profit, y = 1.50x - 17
Cassidy’s profit, y = 1.50(150) - 17
Cassidy’s profit, y = 225 - 17
Cassidy’s profit, y = $208.00

He purchases a total of 150 containers of popcorn to sell. After he sells 15 containers, he will make a total profit, after his upfront costs, of $5.50. Cassidy’s profit, after upfront costs, can be modeled by a linear function in the form y=mx+b.
What is Cassidy’s profit if he sells all of the popcorn?
HInt: Substitute 150 for x to find the profit if all the popcorn is sold.
Determine whether the sample may be biased. Explain.
A reporter wants to know if the majority of the people in a city want a new football stadium to be built using tax funds, so he gets the opinion of 50 random people at a local college baseball game.
A, B, or C?
Answer:
The sample may be biased. The reporter is only getting the opinion of 50 random people at a local college baseball game, which does not represent the opinion of the entire population of the city. Therefore, the results of the survey cannot be used to make a general statement about how all people in the city feel about the new football stadium.

"The school band decided to raise money by holding a car wash. The band spent $32 to buy the needed supplies. They will charge $5 for each car they wash.
Part A: Create a table showing the profit (total money minus expenses) that the band will make for washing 1 through 10 cars. [Table shown]
Part B: What will be the band's profit for washing 40 cars?
Part C: What is the minimum number of cars the band needs to wash to start making a profit?
Part D: Write the linear equation that would represent the profit earned by washing C number of cars."
Answer:
Scroll Down Below...
Step-by-step explanation:
Part A: Table show the profit for washing 1 through 10 machines:| Number of Cars (C) | Total Money Earned | Expenses | Profit 1
| 1 | $5 | $32 | -$27 |
| 2 | $10 | $32 | -$22 |
| 3 | $15 | $32 | -$17 |
| 4 | $20 | $32 | -$12 |
| 5 | $25 | $32 | -$7 |
| 6 | $30 | $32 | -$2 |
| 7 | $35 | $32 | $3 |
| 8 | $40 | $32 | $8 |
| 9 | $45 | $32 | $13 |
| 10 | $50 | $32 | $18 |
|Part B: To find the band's profit for washing 40 convertibles, we can use the undeviating equating:Profit = (Total Money Earned) - ExpensesThe total services gained for washing 40 automobiles is:Total Money Earned = $5 x 40 = $200Substituting the principles into the equating:Profit = $200 - $32 = $168Therefore, the band's profit for washing 40 rides is $168.Part C: The minimum number of buses the band needs to wash to start making a profit maybe contingent upon judgment the point place the profit enhances beneficial. From the table, we can visualize that the band starts making a profit when they wash 7 machines. So the minimum number of buses the band needs to wash to start making a profit is 7.Part D: The uninterrupted equating that shows the profit gained by washing C number of jeeps maybe composed as:Profit = (Total Money Earned) - ExpensesThe total services won for washing C machines is:Total Money Earned = $5CSubstituting the principles into the equating:Profit = $5C - $32Therefore, the undeviating equating illustrating the profit won by washing C number of rides is:Profit = $5C - $32
Answer:
A: see attached
B: $168
C: 7
D: profit = 5C -32
Step-by-step explanation:
You want the profit earned by a school band after spending $32 for supplies when they charge $5 for each car washed.
A: TableThe attachment shows a table of earnings and profit for 1–10 cars and for 40 cars (Part B).
B: 40 CarsThe last line of the attached table shows the profit for washing 40 cars is $168.
The profit for washing 40 cars is $168 because it is the amount resulting from subtracting the expenses of $32 from the revenue of $5 × 40 = $200.
C: Break evenThe highlighted line in the table shows the first positive profit is made by washing 7 cars.
The minimum number of cars the band needs to wash to start making a profit is 7.
D: EquationThe equation for the profit will reflect that profit is the difference between the revenue and the expenses:
profit = 5C -32
__
Additional comment
A spreadsheet is handy for making the table. The (money earned) column is 5 times the (# of cars) column, reflecting the $5 per car charge. The expense is then subtracted to give the value in the profit column. The last line shows it is easy to find the profit associated with any particular number of cars being washed. Effectively, the equation for profit is embedded in the table formulas.
