The value of x is 3
How to solve for x?The given parameters are:
Length = 10cm
width = 2cm
Height = x
The surface area is calculated as;
Area = 2 *(lw + lh + wh)
So, we have:
2 * (10 * 2 + 2x + 10x) = 112
Evaluate the like terms and divide by 2
20 + 12x = 56
Subtract 20 from both sides
12x = 36
Divide by 12
x = 3
hence, the value of x is 3

Solve the equation f(x)=x3+2x2+4x+8 given that one of its roots is x=−2.
Okay, first you need to understand that function of x, (or f(x)) is y.
We now plug in x.
f(-2) or y=-2(3)+(2•2)+4(-2)+8
f(-2)=-6+4+-8+8
f(-2)=-2
When x=-2, y=-2. Lets plug it back in to see if its true.
-2=-2(3) + (2x2) + (4(-2)) + 8
-2 = -6 + 4 + -8 + 8
-2 = -2.

Two side lengths of a triangle are $11$ and $17$. What is the longest possible integer length of the third side of the triangle
The longest possible integer length of the third side of the triangle is 6 < x < 28
The sum of any two sides must be greater than the third side for a triangle to exist
let the third side be x
x + 11 > 17 and x + 17 > 11 and 11 + 17 > x
x > 6 and x > - 6 and x < 28
The longest possible integer length of the third side of the triangle is 6 < x < 28
The length of the 3 sides of a triangle needs to always be among (however no longer the same) the sum and the difference of the opposite two sides. As an example, take the instance of two, 6, and seven. and. consequently, the third side period should be extra than 4 and less than 8.

Answer:
27
Step-by-step explanation:
Let the third side length be s. Then, by the Triangle Inequality, we know that s satisfies the inequalities
[tex]s + 11 & > 17, \\ s + 17 & > 11, \\ 11 + 17 & > s.[/tex]
[tex]\begin{align*} s + 11 & > 17, \\ s + 17 & > 11, \\ 11 + 17 & > s.\end{align*}[/tex]
The first two inequalities hold as long as s > 6 and the third holds if s < 28. The largest possible integer s that satisfies all of these is 27.

bill is replacing his 15ft long by 12 ft wide deck. his new deck will add 5 feet to the length and 4 feet to the width. if a drawing of the new deck uses a scale of 1 inch =2.5 feet, fin the dimensions of the deck in the drawing
The dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.
Given that the length of the previous deck = 15 feet
The width of the previous deck = 12 feet
Since the new deck will add 5 feet to the length and 4 feet to the width,
The length of the new deck = 15 + 5 = 20 feet
The width of the new deck = 12 + 4 = 16 feet
Also given that a drawing of the new deck uses a scale of 1 inch = 2.5 feet.
So, The length of the deck in the drawing = 20/2.5 inches = 8 inches
The width of the deck in the drawing = 16/2.5 inches = 6.4 inches
Therefore, the dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.

Number of ways in which 3 positions can be filled are 2730.
What is permutation and combinations?The number of ways in which objects from a set may be selected, generally without replacements, to form subsets. This selection of subset is called permutation when order of selection is a factor.

⇒Permutation,
[tex]P(n,r) =\frac{n!}{(n-r)!}[/tex]
Now it is given that number of candidates, n = 15
and number of position, r = 3
Hence number of ways positions can be filled-
[tex]P(n,r) =\frac{15!}{(15-3)!}[/tex]
⇒ [tex]P(15,3) =\frac{15!}{12!}[/tex]
⇒ P(15,3) = (15 × 14 × 13)12!/12!
⇒ P(15,3) = (15 × 14 × 13)
⇒ P(15,3) = 2730
∴ Number of ways in which 3 positions can be filled are 2730.

The system of linear inequalities which satisfy the region R are:
y < x - 3.y ≤ -2x + 5.y ≥ x.How to find the inequalities?Mathematically, the standard equation of a straight line is given by y = mx + b.
In order to determine the system of linear inequalities that satisfy the region R, we would identify the points through which the lines passes through.
For the broken line, we have:
y-intercept = 3.
x-intercept = -3.
Points (x, y) = (0, 3) and (-3, 0).
Since the line is broken (not equal to), the inequality is given by:
y < x - 3.
For the other line, we have:
y-intercept = 5.
x-intercept = -5/2.
Points (x, y) = (0, 5) and (-5/2, 0).
(x/-5/2) + y/5 ≤ 1
-2x + y ≤ 5
y ≤ -2x + 5
For the line passing through the origin, we have:
y - x ≥ 0
y ≥ x.

Complete the point-slope equation of the line through-8,-8) and (7, 9)
Answer:
[tex]y = \frac{17}{15}x + \frac{16}{15}[/tex]
Step-by-step explanation:
So the slope-intercept form is given as: y=mx+b where m is the slope and b is the y-intercept (since if you plug in 0 as x, mx will be 0 leaving only b). You can calculate the slope with the slope formula: [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] which is essentially [tex]\frac{rise}{run}[/tex]. So for this example (-8, -8) will be ([tex]x_1, y_1[/tex]) and (7, 9) will be ([tex]x_2, y_2[/tex]).
Plug values into equation:
[tex]\frac{9 - (-8)}{7 - (-8)}[/tex]
cancel out negatives
[tex]\frac{9+8}{7+8}\\[/tex]
Simplify
[tex]\frac{17}{15}[/tex]
The fraction is in the most simplified form unless you want to have a mixed fraction, otherwise you can't do anything else to the fraction.
so now we have the slope we have one part of the equation: [tex]y=\frac{17}{15}x + b[/tex], but now we need to solve for b. This can be done by using either of the points and plugging in x and y, but for this example I'll use (7, 9).
Plug in (7, 9) as (x, y)
[tex]9 = \frac{17}{15}(7) + b[/tex]
Multiply
[tex]9 = \frac{119}{15}+b[/tex]
Subtract
[tex]9-\frac{119}{15}=b[/tex]
Rewrite 9 as a fraction
[tex]\frac{135}{15} - \frac{119}{15} = b[/tex]
Subtract numerators
[tex]\frac{16}{15} = b[/tex]
now we have both pieces of information

Find the equation of the line that passes through the following points: (a, b) and (a, b +1 )
Answer:
The equation for the line which passes through the points given as (a, b) and (a, b+1), is x=a, which represents a vertical line.
Step-by-step explanation:
It is given that a line passes through the points whose coordinates are (a, b) and (a, b+1).
It is asked to find the linear equation which passes through the given points.
To do so, first determine the slope of the given line using the coordinates and the formula for the slope. Accordingly, proceed to find the equation of the given line.
Step 1 of 2
Determine the slope of the line.
The points through which the line passes are given as (a, b) and (a, b+1). Next, the formula for the slope is given as,
[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
Substitute b+1&b for [tex]$y_{2}$[/tex] and [tex]$y_{1}$[/tex] respectively, and a&a for [tex]$x_{2}$[/tex] and [tex]$x_{1}$[/tex] respectively in the above formula. Then simplify to get the slope as follows,
[tex]m=\frac{b+1-b}{a-a}$\\ $m=\frac{1}{0}$[/tex]
b+1. So the equation of the line cannot be found using the general point-slope form equation.
Step 2 of 2
Write the equation of the line.
So, by definition, the line that passes through the given points is a vertical line. Now, as its x- coordinate is a, so the equation of the line is given as x=a.
Consider the following equation.
x^2-3x+2= √ x-2 + 2
Approximate the solution to the equation using three iterations of successive approximation. Use the graph below as a starting point.

The approximate solution of the above equation is: 55/15 (Option A). This is solved using the quartic formula, not quadratic equation.
What is the Quartic Formula?
The quartic formula has up to four various solutions including real and imaginary numbers. Read on for more explanation.
What is the solution to the above question?
First we restate the above equation:
x²-3x+2= √(x-2) + 2
Next we remove square roots
[tex]x^{4}[/tex] - 6x³ + 9x² = x - 2
Add two to both sides
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 = x - 2 +2
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 = x
Subtract X from both sides
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 -x = x -x
→ [tex]x^{4}[/tex] - 6x³ + 9x²+2 - x= 0
Using the Quartic formula to solve the fourth order equation:
a[tex]x^{4}[/tex] + bx³ + cx² + dx + e
The resolution of x is given as:
x = 2.691085, 3.346753
Because the fraction nearest to 3.4 is 55/16
