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
Hope it helped. Pls mark me the BRAINLIEST! Don't fool pls

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.
Hope this helped. Pls mark me the BRAINLIEST!

The graph that shows the translation is given as follows:
Option D.
What are the translation rules?The four translation rules are defined as follows:
Left a units: x -> x - a.Right a units: x -> x + a.Up a units: y -> y + a.Down a units: y -> y - a.For this problem, we have that the translations are given as follows:
2 units left -> 2 is subtracted from each coordinate of x.5 units down -> 5 is subtracted from each coordinate of y.This means that the graph that correctly shows the translation is given by option D.

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.
Step-by-step explanation:
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

Complete Question:
Cassidy is selling popcorn for a fundraiser sale at the price shown.
A photo of a container of popcorn is shown. The price tag reads one dollar and fifty cents.
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.

Which simplified ratio correctly compares 12 yards to 20 feet? 1 yard = 3 feet
please help
Answer:
3/5
Step-by-step explanation:
Given ratio 12 yard to 20 feet,
To simplify the ratio, we first need to find the common multiples of 12 and 20,
to find the common multiples of 12 and 20, we need to factorize 12 and 20.
On factorization, we get 12= 2*2*3 and 20=2*2*5.
Common multiples of 12 and 20 are that is 4.
And now simplifying the given ratio, 12 yard to 20 feet , that is 12/20=3/5
Answer: 3/5
Step-by-step explanation: To simplify the ratio, we first need to find the common multiples of 12 and 20 then once you find the common form there you should have your answer.
