Use Multiplication to Check Division Whole numbers are closed under addition because the sum of two whole numbers is always a whole number. Explain how the process of checking polynomial division supports the fact that polynomials are closed under multiplication and addition.
Answers
You multiply the quotient by the divisor to test polynomial division.
The process of checking polynomial division supports the fact that polynomials are closed under multiplication and addition will be as follow:
A polynomial will make up the quotient (with or without a remainder). We obtain a polynomial whose exponents and coefficients have changed by multiplying this one by the polynomial divisor. As a result, polynomials are closed when multiplied.The divisor normally has two or more words. By multiplying the entire quotient by each term in the divisor, we will be able to multiply the quotient by this using the distributive property. After this step is complete, we must sum the polynomials we had after multiplying them. By doing so, we have a polynomial solution whose coefficients have changed. Polynomials are hence closed under addition.Hence we can by this way we can check polynomial division supports the fact that polynomials are closed under multiplication and addition

Please help 60 points for a rapid answer-In the figure below which of the following is true in circle E?
Answers
Answer:
all 3 options are true : A, B, C
Step-by-step explanation:
warning : it has come to my attention that some testing systems have an incorrect answer stored as right answer for this problem.
they say that A and C are correct.
but I am going to show you that if A and C are correct, then also B must be correct.
therefore, my given answer above is the actual correct answer (no matter what the test systems say).
originally the information about the alignment of the point F in relation to point E was missing.
therefore, I considered both options :
1. F is on the same vertical line as E.
2. F is not on the same vertical line as E.
because of optical reasons (and the - incomplete - expected correct answers of A and C confirm that) I used the 1. assumption for the provided answer :
the vertical line of EF is like a mirror between the left and the right half of the picture.
A is mirrored across the vertical line resulting in B. and vice versa.
the same for C and D.
this leads to the effect that all 3 given congruence relationships are true.
if we consider assumption 2, none of the 3 answer options could be true.
but if the assumptions are true, then all 3 options have to be true.
now, for the "why" :
remember what congruence means :
both shapes, after turning and rotating, can be laid on top of each other, and nothing "sticks out", they are covering each other perfectly.
for that to be possible, both shapes must have the same basic structure (like number of sides and vertices), both shapes must have the same side lengths and also equally sized angles.
so, when EF is a mirror, then each side is an exact copy of the other, just left/right being turned.
therefore, yes absolutely, CAD is congruent with CBD. and ACB is congruent to ADB.
but do you notice something ?
both mentioned triangles on the left side contain the side AC, and both triangles in the right side contain the side BD.
now, if the triangles are congruent, that means that each of the 3 sides must have an equally long corresponding side in the other triangle.
therefore, AC must be equal to BD.
and that means that AC is congruent to BD.
because lines have no other congruent criteria - only the lengths must be identical.

Answers
Using mathematical operations, Betsie should buy the 250 envelopes from Letters2go Shop at a total cost of £319.
How is the total cost determined?To determine the total cost, we first determine the unit cost of an envelope at each shop.
The unit cost is multiplied by the number of envelopes required less the cost of free envelopes at Value World.

Based on the expression, what is the amount, in dollars, Teresa will have in her account 6 months from now? (Ignore the $dollar sign symbol when entering your answer.)
Answers
Answer:
Teresa will have $2500 in her account 6 months from now if she deposits $250 each month.
Step-by-step explanation:
The given expression is:
1000 + 250x
To find the amount Teresa will have in her account 6 months from now, we need to substitute x = 6 in the expression:
1000 + 250(6) = 1000 + 1500 = 2500
Therefore, Teresa will have $2500 in her account 6 months from now if she deposits $250 each month.

What is a loan?A loan is the money that is given to an individual by another person or bank in which the individual is expected to pay back at a particular time with accumulated interest.
The principal amount of the loan = $6,000
The annual interest rate (R) = 6%

What is factorisation?We use the factorisation method to simplify any algebraic as well as quadratic problem by representing in terms of the product of factors rather than expanding the brackets.
Any equation's factors could be an integer, variable, or an algebraic expression.
The given quadratic equation is-
function f(x) = −x² + 20x − 75
Re write the equation.
−x² + 20x − 75 = 0
Divide the whole equation by -1.
x² - 20x + 75 = 0
Factorising the equation.
x² - 15x - 5x + 75 = 0
x(x -15) -5(x - 15) = 0
(x - 15)(x - 5) = 0
Equating each equals to zero,
x = 15 and x = 5.
Thus, the two roots of the given quadratic equation are 5 and 15.
These roots represent that, if these roots are put in the equation the value will come zero.
So, in the context of given question, these roots shows there is no profit incurred in photos.

The ratio of cherry candies to grape candies in a bag is 3:5. After your friend eats half of the grape flavored candies and only one cherry flavored candy, the ratio of cherry to grape candies is 7:6. How many candies are left in the bag?
Answers
Answer:
65
Step-by-step explanation:
I'm not completely sure if this is correct but this is what I got:
cherry candies: c ; grape candies: g
the ratio of the cherry candies to the grape candies is 3:5 so c/g=3/5 so c=3/5g
when you eat 1 cherry candy and half of the grape candies the ratio becomes (c-1)/(g/2)=7/6
I used substitution so now it becomes (3/5g-1)/(g/2)=7/6 if you solve this g will equal to 60. This number means that there was 60 grape candies originally. With this, you can solve for the number of cherry candies that you originally had (which is 36 because the ratio is 3:5)
so now you halve the number of grape candies which is 30 and take one off from the cherry candies which is now 35 (cherry:grape = 7:6 = 35:30)
there are now 65 candies altogether
A ratio shows us the number of times a number contains another number. The total number of candies that are left in the bag is 65.
What is a Ratio?A ratio shows us the number of times a number contains another number.
The ratio of cherry candies to grape candies in a bag is 3:5. Therefore, we can write the ratio of the cherry to grapes as,
Cherry / grapes = 3/5
Multiply both the numerator and the denominator of the ratio with x,
Cherry / grapes = 3x/5x
Therefore, the number of Cherry and grapes in the initial was 3x and 5x, respectively.
Further, it is given that your friend eats half of the grape flavored candies and only one cherry flavored candy, the ratio of cherry to grape candies is 7:6. Therefore, we can write the ratio as,
\(\dfrac{3x - 1}{\frac{5x}{2}} = \dfrac{7}{6}\)
Now, to get the real numbers we can write,
\(\dfrac{3x - 1}{\frac{5x}{2}} = \dfrac{7}{6} \times \dfrac{y}{y}\\\\\dfrac{3x - 1}{\frac{5x}{2}} = \dfrac{7y}{6y}\)
Thus, we got two equations,
3x - 1 = 7y
5x/2 = 6y
Solving the second equation for x,
5x/2 = 6y
5x = 12y
x = 12y/5
Substitute the value of x in the first equation,
3x - 1 = 7y
3(12y/5) - 1 = 7y
y = 5
Furthermore, the total number of candies can be written as,
6y + 7y
= 6(5) + 7(5)
= 30 + 35
= 65
Hence, the total number of candies that are left in the bag is 65.
