You get the next term by adding 3 to the last one, e.g.
25+3=28
28+3=31
...
37+3=40
40+3=43

I think you're asking: "Which does a polygon have more of ... sides or angles ?"
This is a perfect example of where you spent more time and effort
posting your question on the internet than what it would take you
to answer it for yourself.
Can you draw a picture of a triangle ?
You'll see it has 3 sides and 3 angles.
Can you draw a picture of a square ?
You'll see it has 4 sides and 4 angles.
Can you draw a picture of a shape with 5 sides ?
You'll see that it has 5 angles.
Can you draw a shape with 6 sides (like s STOP sign) ?
You'll see that it has 6 angles.
By now, you would be getting the crazy hunch that maybe the
sides and angles of a polygon always happen in the same number.
THEN you would get on Brainly and ask: "I have been working
with some polygons, and I noticed that every polygon I tried had
the same number of angles as it had sides. Is this always true
for any polygon ?"
If I saw that question, I would jump on it with joy, because it feels
so good to help someone who doesn't mind putting some of his
own time and effort into a question.
I would answer "YES !", and then find 15 other characters to fill the minimum.
it depends on what kind of shapes like how many sides
but ex : rectangle has more sides than triangles so some of them yes, and some of them, no

Answer:
Option C is correct
[3,7]
Step-by-step explanation:
Average rate of change(A(x)) of f(x) over an interval [a, b] is given by:
As per the statement:
The average rate of change of f(x) is given by the formula:
we can write this as:
By definition, we have
b = 7 and a = 3
⇒interval = [3, 7]
Therefore, the interval does this formula give the average rate of change for f(x) is, [3,7]

2*0+3y = 6
3y=6
y=2 is the y intercept.
Final answer:
To find the y-intercept in an equation, we set x equal to 0 and solve for y. For the equation 2x + 3y = 6, when x is replaced with 0, it simplifies to 3y = 6. Dividing by 3 gives y = 2, meaning the y-intercept of the line is 2.
Explanation:
The given equation in this question is in the standard form of a linear equation which can be represented in slope-intercept form of y = mx + b, where m is the slope and b is the y-intercept. To find the y-intercept, we'll want to set x equal to 0 and solve for y.
So in this equation of 2x + 3y = 6, we'll set x to 0. That leaves us with 3y = 6. Solve for y by dividing by 3 on both sides. This gives us y = 2, which is the y-intercept.
