The expression x³ 3x² 4x 6 can be expanded to x³ + 3x² - 4x - 6. When this expression is evaluated for x = 3, the result is 24, so the remainder is 0.
The expression x³ 3x² 4x 6 can be expanded to x³ + 3x² - 4x - 6. To find the remainder when this expression is evaluated, we must first substitute in a value for x. For this example, let x = 3. When we substitute 3 for x, the expression becomes 3³ + 3x² - 4(3) - 6. We can simplify this expression by performing the operations in order of operations. First, we can calculate 3³, which is equal to 27. Next, we can calculate 3x², which is equal to 27. Subtracting 4(3) from 27 gives us 15. Finally, subtracting 6 from 15 gives us 9.
The remainder of evaluating
x³ 3x² 4x 6 for x = 3 is 9.

The width of a rectangle is the length minus 5 units. The area of the rectangle is 14
units. What is the width, in units, of the rectangle?
The width of the rectangle is 2 units.
What is the width of a rectangle?Despite having four sides, a rectangle only has two distinct dimensions since the sides are paired. Though the width is often the shorter of these two dimensions, it is more commonly referred to as the horizontal side when the rectangle is shown lying on its side.
Calculation:Given the width of rectangle is length of rectangle - 5 units.
Let us suppose that length of rectangle is y and width of the rectange is y-5.
The formula of area of rectangle is l×b where l and b are length and breadth respectively.
So substituting in the equation we get
[tex]y* (y-5) = 14.\\y^2- 5y = 14\\y^2 - 5y - 14 = 0[/tex]
Solving the above quadratic equation we get y as 7 and -2.
As length cannot be a negative quantity we take length as 7 and it gives us the result that the width is 2 units.

The cost of a phone is reduced by 20%. The new cost is $70.40. What was the original price?
The original price 1. $ 88.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means)
Given;
The cost of the product was reduced by 20%, leaving $ 70.4 as the final price.
Cost of phone after 80% off= $70.40
So, now we will do a cross-multiplication;
If the percent is 80% =70.40
Let, the original price 100% = x
80x = 70.40. 100
80x = 7040
X = 7040: 80

What are the vertical and horizontal asymptotes of F x )= 3x 2 x 2 4?
As given by the question , so here the vertical and horizontal asymptotes are at x = -12 and y = 1.5.
What is vertical asymptote?On a function graph, a vertical asymptote represents the point at which the function is undefined. Take the formula f(x) = 1/x as an illustration. This function's graph exhibits a vertical asymptote at x = 0 since the function is undefined at this value (division by 0 is undefined).
What is horizontal asymptote?A function's horizontal asymptote is a horizontal line on the function graph that the function approaches as the input (x-value) increases or decreases dramatically. Consider the function f(x) = x2 as an illustration. Because the y-values of the function do not converge to a fixed value as x grows very big, the graph of this function lacks a horizontal asymptote.
We must identify the values of x at which the function is undefined in order to determine the vertical asymptotes of the function 3x/(2x+24).So, to find the vertical asymptotes of the function, we need to solve the equation 2x + 24 = 0 for x. so x = -12.
Similarly, To find the horizontal asymptote in case of equal degrees of numerator and denominator i.e 1 in this case, we need to take the ratio of the first coefficients of numerator and denominator respectively which is 3/2 = 1.5.

How do you find the slope of a perpendicular line with an equation and point?
First, by solving for y, convert the equation of the given line into slope-intercept form y=mx+c .You obtain the slope of the equation as m. Since the slopes of perpendicular lines are negative reciprocal, the slope of the line we're looking is the negative reciprocal of the perpendicular equation.
By entering the supplied point into the formula y = mx + b and solving for b, we arrive at the value of b. Consequently, the line's equation is formed.
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by Δy and Δx, respectively.
m = y/x = y/x = change in y/change in x
where "m" represents a line's slope.
Additionally, the slope of the line may be shown as

What are three consecutive odd integers of 57?
The required three consecutive odd numbers that sum up 57 are 17, 19 and 21.
What are consecutive numbers ?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.
Since, we know that any odd number is always of the form (2k +1). We express an odd number in this form because we know that an odd number is not divisible by 2.
Now, the next odd number after (2k+1) will be (2k+3) because if we take (2k+2) then we can see that it is clearly divisible by 2.
So, we can say that the difference between any two consecutive odd numbers is:
= 2k+3 – (2k+1)
=2k+3-2k-1
=2
So, for every two consecutive odd numbers there is a difference of 2.
Now, let us take ‘n’ to be an odd number.
So, an odd number just before n will be (n-2).
And also an odd number just after n will be (n+2).
Since, it is given that the sum of these three consecutive odd numbers is 57. So, we can write the following equation:
n-2+n+n+2=57
3n=57
So, n = 19
The odd number before n will be = n -2 = 19-2 = 17
And the odd number after n will be = n+2 = 19 + 2 = 21
Therefore, The required three consecutive odd numbers that sum up 57 are 17, 19 and 21.

The relative minimum of h(x) occurs at x = 2. Integrals can be used to solve a wide range of problems in mathematics and physics, such as finding the area under a curve
An integral is a mathematical concept that involves the concept of integration, which is a way to find the area under a curve or the volume of a solid of revolution. Integrals can be classified into two types: indefinite integrals and definite integrals.
To find the relative minimum of the function h(x), we need to find the value of x that minimizes the value of h(x).
First, let's find the derivative of h(x). We can do this by applying the chain rule to the function inside the integral:
[tex]h'(x) = (-4 * (t - 2)^2 + 8)' = (-4 * (t - 2)^2 + 8)' = -8 * (t - 2)[/tex]
Next, we need to find the points where h'(x) = 0 or is undefined. Setting h'(x) = 0 and solving for t, we find that t = 2. Substituting this value back into the original expression for h(x), we get:
[tex]h(x) = -4 * (2 - 2)^2 + 8 = 8[/tex]
Since h'(x) is undefined at t = 2, we need to check whether the function is increasing or decreasing at that point. To do this, we can take the second derivative of h(x):
[tex]h''(x) = (-8 * (t - 2))' = -8[/tex]
Since the second derivative is negative at t = 2, this means that the function is decreasing at that point.
