Complete the square
x^2 - 2x - 14 = 0
Answers
To complete the square for the equation x^2 - 2x - 14 = 0, follow these steps:
1. Move the constant term to the right side of the equation: x^2 - 2x = 14
2. Take half of the coefficient of x, square it, and add it to both sides of the equation: x^2 - 2x + 1 = 15
3. Factor the left side of the equation as a perfect square: (x - 1)^2 = 15
4. Take the square root of both sides of the equation, remembering to include both the positive and negative square roots: x - 1 = ±√15
5. Add 1 to both sides of the equation to isolate x: x = 1 ± √15
Therefore, the solutions to the equation x^2 - 2x - 14 = 0 are x = 1 + √15 and x = 1 - √15.
ga rectangular enclosure at a zoo is 35 feet long by 18 feet wide. the zoo doubles the area of the enclosure by adding the same distance to the length and width. what are the new dimensions of the enclosure?
Answers
The new length is 35+10=45 and the new width is 18+10=28.
To Find the Area of a rectangle is length times the width.
Given that enclosure at the zoo is 35 feet long by 18 feet wide. It means the length is 35 feet and the width is 18 feet.
Area of Rectangle=Length × Width
=35×18
=630
The zoo wants to double the area of the enclosure by adding the same distance x to the length and width.
(35+x)×(18+x)=1260
630+35x+18x+x2=1260
x2+53x+630-1260=0
x2+53x-630
Now we will apply the quadratic formula we get
x=10.
The new length is 35+10=45
The new width is 18+10=28.

Let the quantity of the required flour would be x cup
As per the given information, we can write the proportion would be as:
1 1/2 dozen cookies : 1 cup flour = 3 dozen cookies : x cup flour
⇒ (1 1/2) / 1 = 3/x
⇒ (3/2) / 1 = 3/x
⇒ 3/2 = 3/x
Apply the cross-multiplication operation,

The line y=−0.5x+b passes through the points (1,5.5), (3,p), (4,4), and (7,n). Find b, n, and p.
Answers
Step-by-step explanation:
Finding b
If we use the given slope and use one of the points to write the equation in point-slope form (y - y₁) = m(x - x₁)), we can rearrange it to find the y-intercept:
Using (4,4)
⇒ y - 4 = - 0.5 (x - 4)
y - 4 = - 0.5 x + 2
y = -0.5 x + 6
∴ b = 6Calculating 'n' and 'p'
We can find n and p by plugging the points into the newly found equation y = -0.5 x + 6.
For n using (7, n)
since y = -0.5 x + 6
n = -0.5 (7) + 6
∴ n = 2.5For p using (3,p)
since y = -0.5 x + 6
p = - 0.5 (3) + 6
p = - 1.5 + 6
p = 4.5Checking the answer
We can check the answer we got in two ways:
We could also have found n a different way:Using the points (4, 4) and (7, n) as (x₁, y₁) & (x₂, y₂) respectively
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
- 0.5 = (n - 4) ÷ (7 - 4)
- 0.5 = ⁿ⁻⁴/₃ [multiply both sides by 3]
- 1.5 = n - 4 [add four to both sides]
n = 2.5 [this matches the value of n we found]
We can plot the line and see if it goes through the points we found. As seen in the graph below, the line passes through all the points.

Answers
The solution for x is 621.5424 M \(s^{-1}\), with units of molar per second (M \(s^{-1}\)).
To solve for x in the equation x = (6.4×10^3 M^(-2) s^(-1))(0.46M)^3, we can simplify the expression and calculate the result. Let's break it down step by step: x = (6.4×10^3 M^(-2) s^(-1))(0.46M)^3
First, let's simplify (0.46M)^3: (0.46M)^3 = (0.46^3)(M^3) = 0.097336M^3
Now, substitute this back into the equation:
x = (6.4×10^3 M^(-2) s^(-1))(0.097336M^3)
Next, multiply the terms: x = 6.4×10^3 × 0.097336 M^(-2) s^(-1) M^3
When multiplying the terms with the same base, we add the exponents:
x = 6.4×10^3 × 0.097336 M^(-2 + 3) s^(-1)
Simplifying the exponent: x = 6.4×10^3 × 0.097336 M^(1) s^(-1)
Now, multiply the numerical values: x = 621.5424 M s^(-1)
Therefore, the solution for x is 621.5424 M s^(-1), with units of molar per second (M s^(-1)).

The volume of the box is 58 cm³. Therefore, the units of the answer are cm³.
What is volume?Volume is the measure of the amount of 3-dimensional space occupied by an object or substance. It is usually measured in cubic units, such as cubic centimeters (cm3) or cubic meters (m3). Volume is an important concept in mathematics, physics, chemistry, and engineering, and is used to calculate the amount of material needed for a given project.
The volume of the box can be calculated by multiplying the area of the base with the height of the box. The area of the base is 58 cm² and the height of the box is x - 2 cm. Therefore, the volume of the box can be expressed as:
Volume = 58 cm² x (x - 2 cm)

A = amount borrowed
R = interest rate = 12/2 = 6%

An artist is building a pedestal out of wood that will be used to display a piece of sculpture. she plans to cover the pedestal with tile. how much tile will it take to cover the pedestal? cm2
Answers
The amount of tile needed to cover the pedestal will depend on the size and shape of the pedestal. In order to determine how much tile is needed, you will need to measure the surface area of the pedestal.
The pedestal's dimensions are height, breadth, and length.
Multiply the height, width, and length of the pedestal to calculate the surface area.
Multiply the surface area by the number of tiles needed to cover the pedestal. To determine the number of tiles needed, divide the surface area by the area of each tile.
For example, if the pedestal is 2 feet tall, 2 feet wide, and 4 feet long, the surface area is 16 square feet. If each tile has an area of 1 square foot, then it will take 16 tiles to cover the pedestal.
In conclusion, the amount of tile needed to cover the pedestal will depend on the size and shape of the pedestal and the size of the tiles. To determine the amount of tile needed, measure the surface area of the pedestal and then multiply it by the number of tiles needed to cover the pedestal.

Divide the total number of tiles required to cover the pedestal by the surface area. Divide the surface area by the area of each tile to determine the required number of tiles.
The surface area, for instance, is 16 square feet if the pedestal is 2 feet tall, 2 feet wide, and 4 feet long. 16 tiles will be required to cover the pedestal if each tile has a surface area of one square foot.
In conclusion, the dimensions of the tiles and the pedestal's size will determine how much tile is required to cover the pedestal. Multiply the surface area of the pedestal by the number of tiles required to cover it to find the required quantity of tiles.
