Answer: A.
quadratic trinomial
I am pretty sure it is letter B
Step-by-step explanation: https://www.softschools.com/math/algebra/topics/classifying_polynomials/
It is either letter A or letter B.. Because
Polynomials can be classified two different ways - by the number of terms and by their degree.
1. Number of terms.
A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.
A binomial has two terms. For example: 5x2 -4x
A trinomial has three terms. For example: 3y2+5y-2
Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2
Practice classifying these polynomials by the number of terms:
1. 5y
2. 3x2-3x+1
3. 5y-10
4. 8xy
5. 3x4+x2-5x+9
Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial
2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
Examples:
5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.
3x4+4x2The highest exponent is the 4 so this is a 4th degree binomial.
8x-1 While it appears there is no exponent, the x has an understood exponent of 1; therefore, this is a 1st degree binomial.
5 There is no variable at all. Therefore, this is a 0 degree monomial. It is 0 degree because x0=1. So technically, 5 could be written as 5x0.
3x2y5 Since both variables are part of the same term, we must add their exponents together to determine the degree. 2+5=7 so this is a 7th degree monomial.
Classify these polynomials by their degree.
1.7x3+52+1
2.6y5+9y2-3y+8
3.8x-4
4.9x2y+3
5.12x2
Answers 1) 3rd degree 2) 5th degree 3) 1st degree 4) 3rd degree 5) 2nd degree

Find the measure of the indicated angle to the nearest degree
Answer:
A) 18°
Step-by-step explanation:
To find the measure of the indicated angle, we can use trigonometric ratios.
Looking at the triangle, we can see that we are given the lengths of the two legs of the triangle, but not the hypotenuse. Since we are not given the hypotenuse, the sine and cosine ratios would not work since both of them require the length of the hypotenuse. We can use the tangent ratio, since it only requires the lengths of the two legs. Remember:
[tex]tan(?)=\frac{opposite}{adjacent}[/tex]
From looking at the image, we can see that the length of the side opposite to the angle is 3, and the length of the side adjacent to the angle is 9. Thus, we can use 3 as out opposite and 9 as out adjacent:
[tex]tan(?)=\frac{3}{9}[/tex]
Now we solve for ?. Lets take the inverse tan of both sides to get rid of the tan on the left side:
[tex]?=tan^{-1}(\frac{3}{9})[/tex]
And we get:
? ≈ 18.4349488° ≈ 18°
So the answer would be 18°, or A.
I hope you find my answer to be helpful. Happy studying.

Step-by-step explanation:
find slope and y-intercept form
Answer:
Slope; -1
y-intercept: (0, 3)
Step-by-step explanation:
The y-intercept is the point at which the line crosses the y-axis. Start at the origin (0, 0) and count the number of squares up to the y-intercept: 3.
So the y-intercept is (0, 3).
Again starting from the origin (0, 0), count the number of squares to the x-intercept, which is where the line crosses the x-axis. Again, that number is 3.
Thus, the slope of this line is m = rise / run = -3 / 3 = -1. A quick glance at the graph shows that y decreases as x increases, which confirms that the slope is negative.
13. One kilogram is equal to 1.000 grams
How many kilograms equal 2,570
grams?
A 257 kilograms
25.7 kilograms
2.57 kilograms
0.257 kilogram
Answer quick PLZZ no website
Answer:
2.57
Step-by-step explanation:
So we know that 1 kg equals to 1000 grams in this case however we have 2570 and to get them to kilograms you can go ahead and divide that by 1,000 because 1000 grams equals to 1 kg whenever you divide 2570 by 1,000 you end up getting 2.57 and that will be your answer.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
42°
(8x+14)
60°
Answer:
x = 8
Step-by-step explanation:
the sum of all three interior angles in any triangle = 180°
42° + 8x + 14° + 60° = 180°
8x = 180° - 42° - 14° - 60° = 64°
x = 8
John has 8 different flags that he wants to hang on the wall. How many different ways can the flags be arranged in a row?
Answer:
40,320 different ways
Step-by-step explanation:
Here, we want to arrange 8 flags in a row
In the row, there will be 8 places
The first place has 8 flags to be chosen from
The second place has 7 and like that
So mathematically, the number of ways that we can arrange the flags is 8 factorial ways
We have this as:
8! = 40,320 different ways

Finish solving the equation -13y + 33 = 7.
Answer:
y = 2
Step-by-step explanation:

add -13y to each side of the equation:
33 = 13y + 7
subtract 7 from each side:
13y = 26
divide both sides by 13:

Prove that the given quadrilateral is a square. show all the work
Answer:
A square is defined as a quadrilateral with 4 sides of the same length and 4 right angles. To verify the lengths of the sides, you can use the distance formula. To find the angles, you can use the slopes of the line segments and make sure sides that form an angle have opposite reciprocal slopes.
Step-by-step explanation:
First, find the coordinates of each point. You're provided with the scale and you can just count, but to make it easier, you can label the axes.
A: (0,8)
B: (6,6)
C: (4,0)
D: (-2,2)
The distance formula is used to find the distance between any two points on the coordinate form. Here it is:
d=sqrt((y2-y1)^2 + (x2-x1)^2)
d=distance, and (x1, y1) and (x2, y2) are the points.
Find the length of each side. I'll demonstrate with two sides, AB and BC.
AB: (x1,y1)=(0,8) and (x2,y2)=(6,6)
d=sqrt((6-8)^2 + (6-0)^2)
=sqrt((-2)^2 + 6^2)
=sqrt(4+36)
=sqrt(40)=2sqrt10
BC: (x1,y1)=(6,6) and (x2,y2)=(4,0)
d=sqrt((4-6)^2 + (0-6)^2)
=sqrt((-2)^2 + (-6)^2)
=sqrt(4+36)
=sqrt(40)=2sqrt10
Do the same thing with sides CD and AD, you'll see that they both also have a length of 2sqrt10 inches. (You don't really have to simplify, I just like to.)
To verify if the sides are perpendicular, you need to find the slopes of the sides and make sure that the product of the slopes of each pair of sides that form a vertex is -1. In other words, each pair of sides that form a vertex have to have opposite reciprocal slopes. I'll demonstrate with 2 vertecies, A and B.
To find the slope, you have to use the formula m=(y2-y1)/(x2-x1). m is the slope, and again, (x1, y1) and (x2, y2) are the points you're plugging in.
To find the measure of angle A, you need to find the slopes of sides AD and AB. (These are the sides that meet to form the angle.)
AD: (x1,y1)=(0,8) and (x2,y2)=(-2,2)
m = (2 - 8)/(-2 - 0)
= -6/-2
= 3
AB: (x1,y1)=(0,8) and (x2,y2)=(6,6)
m = (6 - 8)/(6 - 0)
= -2/6
= -1/3
So AD has a slope of 3 and AB has a slope of -1/3. Now you need to make sure they have a product of -1.
-1/3 * 3 = -1
So yes, it works! As I mentioned before, you can also think of them as opposite reciprocals.
The reciprocal of 3 is 1/3. The opposite of 1/3 is -1/3. So yes, the sides are perpendicular.
Let's do it again with angle B. We have to find the slope of BC now, since we already know the slope of AB.
BC: (x1,y1)=(6,6) and (x2,y2)=(4,0)
m = (0 - 6)/(4-6)
= -6/-2
=3
So the slope is exactly the same as the slope of AD. A square is a parallelogram, so it has two pairs of opposite parallel sides. We already verified that 3 and -1/3 are opposite reciprocals, so we now know that angle B has a measure of 90 degrees as well. You can do the same for angles C and D. That way, you'll have proven that all the sides have the same length and all the angles measure 90 degrees-- so the quadrilateral ABCD matches the definition of a square.
Hope this helped!
Use the model to show why 522 is divisible by 9.
522 contains 9 as one of its factor, that's why it is divisible by 9.
What is Factor?A divisor of an integer n, also called a factor of n, is an integer m that may be multiplied by some integer to produce n.
Here given number = 522
Divisor = 9
Now, factors of 522 = 2 X 3 X 3 X 29
= 2 X 9 X 29
(factors of 522)/ 9 = (2 X 9 X 29)/9
= 2 X 29
= 58
Thus, 522 contains 9 as one of its factor, that's why it is divisible by 9.

What we have here is a bisected angle. What this means is that an angle is being cut in half to create multiple angles. In this case angle E has been bisected. Since that is the case, angles 1 and 2 are equivalent to each other. Now that we know this we can solve for x.
