Can someone explain me how to do this
8) v = -3
9) m = 4
Explanation:
8)
[First distribute the factored terms on the left side of the equation]
2(v + 4) + 3(4v + 5) = -19 →
2(v) + 2(4) + 3(4v) + 3(5) = -19 →
2v + 8 + 12v + 15 = -19 →
[Next, add the like terms together]
(2v + 12v) + (8 + 15) = -19 →
14v + 23 = -19 →
[Subtract 23 from both sides to isolate the constant term]
14v + 23 – 23 = -19 – 23 →
14v = -42 →
[Lastly, divide both sides by 14 in order to obtain the value of v from the coefficient of 14 in 14v]
14v / 14 = -42 / 14 →
v = -3
9)
[Start by distributing the factored term on the left side of the equation]
2(m – 1) = 10 – m →
2m – 2 = 10 – m →
[Next, add m to both sides in order to isolate the m term and remove -m from the right side of the equation]
2m – 2 + m = 10 – m + m →
3m – 2 = 10 →
[Add 2 to both sides to isolate the constant term and remove -2 on the left side of the equation]
3m – 2 + 2 = 10 + 2 →
3m = 12 →
[Finally, divide by 3 on both sides in order to reduce the coefficient of 3 in 3m to get m]
3m / 3 = 12 / 3 →
m = 4

A rectangle has sides measuring (4x + 5) units and (3x + 10) units.
Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points)
Part B: What are the degree and classification of the expression obtained in Part A? (3 points)
Part C: How does Part A demonstrate the closure property for polynomials? (3 points)
Part A
Like with any other rectangle, we multiply the length and width to get the area
This applies even when we have algebraic expressions like this (recall that x is simply a placeholder for a number).
So,
area = length*width
area = (4x+5)*(3x+10)
area = w(3x+10) ..... replace (4x+5) with the variable w
area = 3xw + 10w ..... distribute
area = 3x(4x+5)+10(4x+5) .... plug in w = 4x+5
area = 3x*4x+3x*5 + 10*4x+10*5 .... distribute again
area = 12x^2+15x + 40x+50
area = 12x^2+55x+50
Answer: 12x^2+55x+50
=======================================================
Part B
The degree of any single variable polynomial is the largest exponent. In this case, the largest exponent is 2. This 2nd degree polynomial is considered a quadratic. Because we have three terms, this quadratic polynomial is also a trinomial. So there are many ways to describe the result of part A. Possibly the quickest way to describe it is to say "quadratic trinomial" to say all that has been mentioned in this paragraph.
Answers:
Degree = 2Classification = quadratic trinomial=======================================================
Part C
The concept of closure is the idea of taking two objects of the same type, applying some operation to them, and getting an output object of the same type.
Admittedly that last paragraph is a bit vague so I'll go over a few examples.
If we take any two integers and add them up, then we get another integer. This shows integers are closed under addition.We can also multiply any two whole numbers to get some other whole number. This is another example of closure.A non-example would be dividing whole numbers. Something like 10/2 = 5 is a whole number but 10/3 = 3.33 is not. This shows that integers are not closed under division. We don't always get a whole number output.
With polynomials, multiplying any two of them will result in some other polynomial. It's basically using the two examples in the bullet points and building upon them. That's the short version of why polynomials are closed under multiplication.
For this particular problem, (4x+5), (3x+10), and 12x^2+55x+50 are all polynomials.
-----------
In terms of notation,
polynomialA * polynomialB = polynomialC
This notation hopefully shows that multiplying any two polynomials leads to another polynomial.
Refer to this previous problem I answered
https://brainly.com/question/24065851
Specifically, the top of part C talking about a coin machine should hopefully help if any of the concepts here don't make sense. If neither this current page nor the link helps, then let me know and I'll try to rephrase things another way.

A set of integers each is greater than 40 and less than 46. List the members.
Answer:
{41 , 42 , 43 , 44 , 45}
Answer:
Set (x) = {41, 42, 43, 44, 45}
Step-by-step explanation:
Given statement,
→ A set of integers each is greater than 40 and less than 46.
Now the set will be,
→ 40 < x < 46
Then the members of the set are,
→ 40 < x < 46
→ 40 < 41 < 46
→ 40 < 42 < 46
→ 40 < 43 < 46
→ 40 < 44 < 46
→ 40 < 45 < 46
The list of required integers are,
→ 41, 42, 43, 44, 45
→ {41, 42, 43, 44, 45}
Hence, this is the correct answer.

0.00000604
In scientific notation
0.00000604 = 6.04 × 10 ⁻⁶
Numbers in scientific notation get written in the form 1.23... × 10ⁿ, so it's a matter of counting how many times you multiply or divide by 10 in order to move the decimal point to the right position.
The number 0.00000604 has 3 significant digits, so you want to end up with 6.04, and to do that you need to move the decimal point 6 places to the right:
0.00000604
= 0.0000604 × 10 ⁻¹
= 0.000604 × 10 ⁻²
= 0.00604 × 10 ⁻³
= 0.0604 × 10 ⁻⁴
= 0.604 × 10 ⁻⁵
= 6.04 × 10 ⁻⁶

Find the value of x in the given right triangle
hi <3
you can use the sine rule in this.
first calculate the missing angle in the triangle.
we know the angles in a triangle sum to 180 so:
180 - 37 - 90 = 53
now, simply input these values into the sine rule
10/sin(53) = x/sin(37)
rearrange for x:
x = (10/sin53) x sin37
solve to get your answer of:
x = 7.5
hope this helps :)
Answer:
tanx=opposite side
adjacent side
tan(37)=x
10
x=tan(37)x10 (take cross multipication)
x=(0.753554)x10
x=7.53554

7) The sum of Wan Yee's and her mother's age is 60. Two years ago, her mother was three times older than Wan Yee. Calculate (a) Wan Yee's age now.
(b) her mother's age when she was born.
Answer:
1) 130 degrees and 50 degrees 6) a price of a chair is 40, a price of the table is 80 7) a) 16 b)28
Step-by-step explanation:
1) Let it be that the first angle is x, The second one is y
1/5(x+y)=36- the first equation
1/2(x-y)=40- the second equation
The equations are simultaneous
x+y=180 and x-y=80
x+y+x-y=180+80
2x=260
x=130
y=50
6) The cost of a chair is x, the cost of table is y
6x+3y=480 2x+y=160
8x+y=400
8x+y- (2x+y)=400-160
6x=240
x=40
2*40+y=160
y=80
7) The Wan's age is x, the mother's age is y
x+y=60 x=60-y
Two years ago mother's age was y-2, when Wan;s age was x-2
y-2=(x-2)*3
y-2= (60-y-2)*3
y-2= (58-y)*3
y-2=174-3y
4y=176
y= 44
x=60-44=16- Wan's age now
44-16=28- her mother's age when she was born
