Answer:
After finding like terms and solving, we get [tex]\mathbf{3x^2+3x+16}[/tex]
Step-by-step explanation:
We need to find like terms and simplify the expression [tex]4- 2x + x^2 + 5x + 12 + 2x^2[/tex]
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:
[tex]4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16[/tex]
So, after finding like terms and solving, we get [tex]\mathbf{3x^2+3x+16}[/tex]
Note: In the question given we have - and + sign with the term 5x i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:
[tex]4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16[/tex]
So, the answer will be: [tex]\mathbf{3x^2-7x+16}[/tex]
12 x^{5} y^{7} and 7 x^{2} y^{9}
Answer:
19x^7y^16
Step-by-step explanation:
And usually means to add, so combine your like terms:
12x^5y^7 + 7x^2y^9
12 + 7 = 19
x^5 + x^2 = x^7
y^7 + y^9 = y^16
Answer:
Step-by-step explanation:
(12x⁵ y⁷) * (7x²y⁹) = (12*7) * (x⁽⁵⁺²⁾ ) (y⁽⁷⁺⁹⁾)
= 84x⁷y¹⁶
In exponents multiplication, if base are same, then add the powers.
xᵃ * xᵇ = x⁽ᵃ⁺ᵇ⁾

Answer:
m∠6=68°
Step-by-step explanation:
∠1 and ∠2 are supplementary angles, which means they add up to 180°
180-112=68
∠2 and ∠6 are corresponding angles, so they are the same
m∠6=68°
WILL RATE THE BRAINLIST Explain how you can prove your observations in question 3 using a traditional proof. You don't need to develop the steps of the proof; simply describe an approach that you might use. Which theorems might appear in your proof? (Hint: Use the two diagonals of the parallelogram to assist you in describing an approach.)
Answer:
Rectangles are parallelograms. By definition, opposite sides are congruent and all four angles have the same measure. Drawing the two diagonals of a rectangle divides the rectangle into triangles. If I choose a pair of triangles that each have a different diagonal for a side, I can prove them to be congruent. If the triangles are congruent, the corresponding sides (diagonals of the rectangle in this case) are also congruent.

========================================
Explanation:
When we add matrices, we must first make sure they are the same dimensions. In this case, both are 2x3 matrices, so we can add them.
To add matrices, you add the corresponding components.
For example, in the first row, first column, we have B+A = -2+4 = 2. So the value 2 will go in the first row, first column, of the answer matrix.
The other elements are handled in a similar fashion.

If the function f(x) = 4x+2 and g(x) = 5/2x-4 then which of the following is a false statement?
1) f(0) > g(0)
2) f(-4) = g(-4)
3) f(6) = g(12)
4) g(2) > f(2)
Answer:2
Step-by-step explanation:
The condition of the function g(2) > f(2) is incorrect. Then the false statement is D.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
If the function f(x) = 4x + 2 and g(x) = (5/2)x - 4.
The value of the function at x = 0, will be
f(0) = 4 × (0) + 2 = 2
g(0) = (5/2) × (0) - 4 = -4
The condition f(0) > g(0) is correct.
The value of the function at x = -4, will be
f(-4) = 4 × (-4) + 2 = -14
g(-4) = (5/2) × (-4) - 4 = -14
The condition f(-4) = g(-4) is correct.
The value of the function f(x) at x = 6 and the value of the function g(x) at x = 12, will be , will be
f(6) = 4 × (6) + 2 = 26
g(12) = (5/2) × (12) - 4 = 26
The condition f(6) = g(12) is correct.
The value of the function at x = 2, will be
f(2) = 4 × (2) + 2 = 10
g(2) = (5/2) × (2) - 4 = 1
The condition g(2) > f(2) is incorrect.
Then the false statement is D.

Answer:
2/6 or 1/3 simplified
Step-by-step explanation:
First multiply the numerators which is the top number of both fractions, which for this equation is 1 and 2 so 1x2=2. So your final fraction would have a numerator of 2 unless simplified. Next, multiply the denominators which are the bottom numbers of the fraction for this one its 2 and 3 so 2x3=6. Your final fraction is 2/6, if simplified 1/3.

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for play. Each pair of wings is made with 3/4 yard of fabric. The fabric cost $8 dollars per yard. Yo apply properties of multiplication in the following steps to find the total cost of the fabric. 3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with write your answer in the space below
Answer:
It would cost $6 per butterfly wing, which multiplied by 13, gives 78.
Step-by-step explanation:
Treat 1 yard of fabric like the fraction 4/4, if this 1 fabric is equal to $8, then 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13. It's easier this way because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4. This way we can simplify in a relatively easier way.
Answer:
he will need 9.75 yards of fabric i got that from 3/4 x 13= 9.75.
it will cost 78 dollars to buy all the fabric to make the wings. 6x13=78
instead of using 3/4 per butterfly wing we round it to 4/4 that way instead of having to find the price of 3/4 you get the answer and just take 2 dollars for every wing

u= 5i-2j+3k v= -2i+3k
Find a vector that is in the direction of the vector v , whose magnitude is twice that of vector u
9514 1404 393
Answer:
(-4√494)/13i +(6√494)/13k ≈ -6.8388i +0j +10.2585k
Step-by-step explanation:
To answer this question, you need to know two things:
1) the direction of vector v
2) the magnitude of vector u
__
direction of v
A direction is specified by a "unit vector", one with the proper ratio of components, and a magnitude of 1. It is found from a given vector by dividing that vector by its magnitude.
The unit vector in the v direction is ...
v/|v| = (-2i +3k)/(√((-2)² +3²) = (-2i +3k)/√13
__
magnitude of u
The magnitude of vector u is ...
|u| = √(5² +(-2)² +3²) = √38
__
Then the desired vector is ...
(2|u|)(v/|v|) = 2√38(-2i+3k)/√13 = (-4√494)/13i +(6√494)/13k
_____
Additional comment
We have chosen to "rationalize the denominator" by writing √(38/13) as (√494)/13.

What percentage of the total variation in test scores is not explained by the linear relationship between years of study and test scores?
Answer:
Check explanation section.
Step-by-step explanation:
So, we have the following parameters or information from the question above:
=> that the regression equation is Score = 31.55 + 10.90 Years.
So, the regression equation is in the form of mx + c.
Thus, the coefficient that is constant = 31.55 and the coefficient that shows or represents the years = 10.90.
=> Also, we have the value which is most important in this question that is the coefficient of Determination which is represented as R-sq and has the value of 83%.
The percentage of the total variation in test scores is NOT explained by the linear relationship between years of study and test scores = 100% - 83% = 17%.
For the percentage of the total variation in test scores is explained by the linear relationship between years of study and test scores = R- sq = 83%.

Step-by-step explanation:
4x5=20/// 20-12=8// 8+2=10 and there you go 10 is your answer
The amount of milk left after making the pancakes is 52 fluid ounces.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, Stacy has 2 quarts of milk.
Since there are 32 fluid ounces in one quart, it follows:
1 quart = 32 fluid ounces
2 quart = 64 fluid ounces
Therefore, Stacy has 64 fluid ounces of milk.
Now, she used 12 fluid ounces of milk in making pancakes, therefore, the amount of milk left after making the pancakes is:
64 - 12
= 52
Hence, the amount of milk left after making the pancakes is 52 fluid ounces.
