Hello there. To solve this question, we'll have to remember some properties about dividing polynomials.
Given the polynomials, we want to evaluate the division:
[tex](1+3x+x^4)\div(3-2x+x^2)[/tex]Rewriting it the way we perform long division:
We start with the higher degree terms, namely x^4 and x².
Dividing x^4 by x², we get x². Now we multiply every term from the division by this factor and subtract from the term being divided.
Now, we have a 2x³ as the higher degree term from the term being divided. Dividing it by x², we get 2x. Multiply each term of the divisor and subtract from it.
Finally, the highest degree term from the term being divided is x². Dividing it by x², we get 1. Multiply each term of the divisor and subtract it from the dividend.
Now, the highest degree term from the dividend is -x, when the highest degree term from the divisor is x². We cannot proceed with the long division anymore.
It means that we have a quotient:
[tex]x^2+2x+1[/tex]And a remainder:
[tex]-x-2[/tex]Notice if we rewrite it as:
[tex]x^4+3x^2+1=(x^2-2x+3)\cdot(x^2+2x+1)-x-2[/tex]We have the division P(x)/D(x) written in the form:
[tex]P(x)=D(x)\cdot Q(x)+R(x)[/tex]Where Q(x) and R(x) are the quotient and remainder polynomials.

Use integers or fractions for any numbers in the equation.)b) The equation of the line in standard form is(Type your answer in standard form.)
Answers
For this type of question the first step is to calculate the slope of the line given by th equation x+2y=7, for this we recall the slope intercept form ( y=mx+b) and put the equation in that form
[tex]y=-\frac{x}{2}+\frac{7}{2}[/tex]Then, m=-1/2. Now, since the equation of the line we are looking for is parallel to the previous line the slope must be the same, now we recall the point slope equation
[tex]\begin{gathered} (y-y_1)=m(x-x_1) \\ \end{gathered}[/tex]Substituting m=-1/2, and recalling that the line is passing through (-3,4) we get that the point slope equation the line is :
[tex]\begin{gathered} y-4=-\frac{1}{2}(x-(-3)) \\ y-4=-\frac{1}{2}x-\frac{3}{2} \end{gathered}[/tex]Finally to put it in the slope intercept form, we solve the equation for y:
[tex]y=-\frac{1}{2}x+\frac{5}{2}[/tex]For part b) we recall that the standard form of the equation of a line is:
[tex]\begin{gathered} C=Ax+By \\ \text{where C, A and B are real and whole numbers if possible} \end{gathered}[/tex]Now, we solve for the constant of the equation:
[tex]\begin{gathered} \frac{5}{2}=y+\frac{1}{2}x \\ 5=2y+x \end{gathered}[/tex]The last equation is the standard form of the equation of the line.

Henry is younger than Cameron. Their ages are consecutive odd integers. Find Henry's age if the sum of Henry's age and 2 times Cameron's age is 85.
Answers
Since we used x and x+2 as consecutive odd integers. "x" to represent Henry's age, Henry's age is 27. Since we used the expression "x+2" to represent Cameron's age, Cameron's age is "27+2" which is just 29.
How to do age sums?So the consecutive odd integers, just means they're separated by a value of 2. This can be generally expressed as "a and a+2" where the these two values would be consecutive odd integers assuming "a" is an integer.
So let's express the Henry's age as the variable "x", since it's unknown. Since Cameron is older, and by definition of a consecutive odd integer, Cameron's can be expressed as "x+2"
So the equation we need to set up is 2(Cameron's age) + (Henry's age) = 85
So we can substitute variables we defined to express Cameron and Henry's age:
2(x+2)+x= 85
Distribute the 2:
2x+4+x
Add like terms:
3x+4=85
Subtract 4 from both sides:
[tex]3x= 81[/tex]
Divide both sides by 3:
x=27
Since we used "x" to represent Henry's age, Henry's age is 27. Since we used "x+2" to represent the Cameron's age, Cameron's age is "27+2" which is just 29.

Given that Owen moves half the number of boxes moved by Ariana.
So you can put 2 in the left side upper box, and 1 in the left side lower box.
Now, it is mentioned that Owen mobes 12 boxes. So the corresponding number of boxes moved by Arianna is to be obtained.
So you have to put 12 in the right side lower box. And a variable (say 'x') in the right side upper box.
The vaue of 'x' is to be calculated.
Cross multiply the terms,

What is the slope of a line perpendicular to the line whose equation is 3x-12y=-108
Answers
Answer:
-4
Step-by-step explanation:
Given:
Equation of line is 3x-12y = -108.To Find:
Slope of line perpendicular to the given line.Concept used:
For a line ax+by+c = 0 , the slope is equal to -a/b.Slope of a line perpendicular to a line say ax+by+c = 0 will be b/a.For the given equation, we have
a = 3, b = -12 and c = 108
So, Slope of line perpendicular to given line = -12/3 = -4
So, the slope of required line is -4.
The slope of a line perpendicular to the line whose equation 3x - 12y = - 108 will be negative 4.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation is given below.
3x - 12y = - 108
Convert the equation into a slope intercept, then we have
3x - 12y = - 108
12y = 3x + 108
y = (1/4)x + 9
The product of the slopes of the perpendicular line will be a negative one. Then we have
(1/4)m = -1
m = - 4
The slope of a line perpendicular to the line whose equation 3x - 12y = - 108 will be negative 4.

For equation (x- 7) = √36 value of x:
x - 7 = √(6)²
x - 7 = 6
x = 13
For equation (x- 7) = -√36 value of x:
x - 7 = -√(6)²
x - 7 = - 6
x = 1
∴ value of x could be 13 and 1 both.

24. Jenna wants to purchase a new guitar for $375. She currently has $45 in her savings account. If she plans to save $35 each week, how many weeks will it take her to save enough money to purchase the guitar? Choose the inequality that best represents this situation. A 45 + 35x < 375 B 35 + 45x < 375 C 45 + 35x > 375 D 35 + 45x > 375
Answers
Here, we want to select the inequality that best represents the situation
Let the number of weeks be x
Total value saved in x weeks at $35 per week will be 35 * x = 35x
Adding this to what she had initially, the total expression becomes 35x + 45
This sum must be the same or greater than what she plans to save
The inequality is thus;

The miles Jack has driven, y, varies directly with x, the number of hours driven. If Jack drove 175 miles in 2.5 hours, find the number of hours it would take Jack to travel 665 miles.
Answers
If the miles Jack has driven, y, varies directly with x, the number of hours driven. If Jack drove 175 miles in 2.5 hours, the number of hours it would take Jack to travel 665 miles is 9.5 hours.
Determining the number of hours to travelLet x represent the number of hours it would take Jack to travel
Formulate an equation
175 / 2. 5 = 665 / x
The denominator cannot equal 0 because the fraction is defined
so,
x ≠ 0
Hence,
1750 × 25x / 25 = 665 × 25x /x
Reduce the fraction
1750x = 665 × 25
1750x = 16,625
Divide both side by 1750x
x = 16,625 / 1750
x = 9.5
Therefore it will take Jack 9.5 hours.

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Suppose 2 pens cost 10 dollars, therefore 1 pen costs (10/2) = 5 dollars.
From this unitary value, we can determine the cost of any no. of pens.
Given, Jack drove 175 miles in 2.5 hours.
∴ In one hour Jack can drive (175/2.5) miles.
= 70 miles.
So, to travel 665 miles Jack needs (665/70) hours.
= 9.5 hours or 9 hours and 30 minutes.
