Just answer questions 12 and 13 !
Answer:
Step-by-step explanation:
12. We have : angle ABF = angle ABE + angle FBE = 2(w+11) + angle FBE = 8w - 6
-> angle ABE = 8w - 6 - [2(w+11)] = 8w - 6 - 2w - 22 = 6w - 28.
13. As we can see, angle EBA and angle EBC is a linear pair, therefore they're supplementary angles, adding up to 180.
-> 3r + 10 + 2r - 20 = 180
5r - 10 = 180
r = 38.
So, angle EBF = 2r - 20 = 76 - 20 = 56.
(pls just don't blur the question next time cause im very confused why the 2 angles are marked equal)
If you multiply two polynomials, will you always get a polynomial? Try combining some polynomials to answer your question. Use the ones given by your teacher or make up your own polynomials. Keep a record of what polynomials you tried, and the results. When you think you have an answer to your question, explain your reasoning using equations, graphs, visuals, calculations, words, or in any way that will help others understand your reasons.
Polynomials are closed under the multiplication operation, meaning that the result of the multiplication between two polynomials will always be a polynomial.
How to multiply polynomials?To multiply polynomials, we first apply the distributive property, multiplying all terms, then we combine the like terms, that is, adding all the terms that have the same exponents.
Since all the factors of the multiplications will be of polynomial terms, the results of the multiplication will be polynomial, and so will the like terms combined, hence polynomials are closed under the multiplication operation.
One example of multiplication of polynomials is given as follows:
(x² - 1)(x² + 1) = x²x² + x² - x² - 1 = x^4 - 1.

Answer: 5/3
Step-by-step explanation:
The scale factor is the same as the ratio of the length of a side of the image to the length of the corresponding side in the preimage.
We know that N'Q'=10 and NQ=6, so the scale factor is 10/6 = 5/3.

I don't know.
The table that represents a proportional relationship between x and y is table 2.
What is a proportional relationship?A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor.
A proportional relationship is one in which two quantities vary directly with each other.
For example,
y = kx
where,
k = constant of proportionality
You can tell if a table shows a proportional relationship by calculating the ratio of each pair of values.
If those ratios are all the same, the table shows a proportional relationship.
Therefore, let's calculate the ratios of the table
1 / 155 / 75 = 1 / 158 / 120 = 1 / 1510 / 150 = 1 / 15Hence, the table 2 has a proportional relationship.

Step-by-step explanation:
3) Isaac has 18 coins, all quarters and nickels. The total value of the coins it $3.50.
Determine the number of quarters and the number of nickels that Isaac has.
By using the method subtraction,
1 quarter is 0.25
1 nickel is 0.05
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given that,
Isaac has 18 coins, all quarters and nickels.
The total value of the coins it $3.50.
Let the quarters be x and nickels be y
x+ y= 18
x= 18 - y... equation 1
1 quarter is 0.25
1 nickel is 0.05
So,
0.25x+ 0.05y= 3.50
substitute x value in above equation
0.25(18-y)+0.05 = 3.50
4.5-0.25y+ 0.05 = 3.50
4.55 - 3.50 = 0.25y
1.05= 0.25y
y= 4.2
y in equation 1
x= 18 - y
x= 18-4.2
x= 13.8

The pages read by Luis, Dayja and Michael read all together is 252.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
The conditions is,
Luis read 75% more pages than Dayja, and Dayja read 75% more pages than Michael.
Total pages read by Dayja = 84
Now,
Since, Luis read 75% more pages than Dayja.
So, The pages for Luis = 75% of 84
= 75/100 × 84
= 6,300 / 100
= 63
Thus, Pages for Luis = 84 + 63
= 147
And, Number of pages read by Michael = 84 - 63
= 21
Thus, Number of pages read by Michael = 21
So, Total number of pages read by Luis, Dayja and Michael all together is;
= 84 + 147 + 21

90 = 5p + 2 + 3p
2. Combine Like Terms
90 = 5p + 2 + 3p
90 = 8p + 2
3. Subtract 2 from both sides

The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares. The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given Data
A function rule for the area of a rectangle with a length 7 m more than three times its width.
Area of rectangle = Length(Width)
Area of function = (w) (3w+7)
Area of function = 3w² + 7w
If w = 3m
Area of function = 3(3)² +7(3)

How to find the equation of a line?The equation of a line can be express as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line passes through the points (2, 11) and (-8, -18).

m = - 29 / - 10
m = 29 / 10
Therefore, let's find the y-intercept using (2, 11)
The equation is as follows:
11 = 29 / 10(2) + b
11 = 58 / 10 + b
b = 11 - 58 / 10

Urgent | Find the angles of the following shape
Step-by-step explanation:
easy so first you are going to subtract 130 from 180 since any angle that is made on a straight line segment if subtracted you get the answer of the other angle
180-130 =50
I want you to draw this diagram on paper and extend the line S that is 50° since we know the angle SRQ =130
Now you will be able to see a Z formation PQR and the other half of the S is making a Z formation the interior angles of a z formation are always equal to each other
so the interior x =50°
extend the line P or Q out wards that will also be equal to the other side now since it also makes a Z formation
As we know that the angle SRQ is equal 130 we will half it or divide it by 2 the answer will be 65
one angle in R angle will be 65 while the other one will also be 65
Now we know two angles in the triangle PQR and one angle in triangle PRS
applay the formula that all interior angles sum =189
x + 65 + z =180 (name the left unknown angle z)
50 + 65 + z= 180
105+ z =180
z=180-105
z=75
we now all the angles in the triangle x
y angle =65 again apply the z formation to get the answer
