The simplified form of the expression 2(x+14)+(2x-14) is 4x + 14.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is a number used before a phrase.
Given:
An expression,
2(x+14)+(2x-14).
Simplifying,
2(x+14)+(2x-14),
= 2x + 28 + 2x - 14
= 4x + 28 - 14
= 4x + 14
Therefore, the solution is 4x + 14.

if your average stride length is 2.6 feet how many strides will it take you to walk to grandparents house
The distance from your house to your grandparents house is 3.67 miles or 19377.6 ft.
So the total number of strides needed would be:
strides needed = 19377.6 ft / (2.6 ft / stride)
strides needed = 7,452.92 = 7,453 strides

What is the equation for the linear model in the scatter plot obtained by choosing the two points closest to the line.
A. y= -1.5x + 6
B. y= 1.5x +6
C. y= 1.5x - 12
D y=2x+6
Option B is correct. The required for the linear model in the scatter plot is y = 1.5x + 6
The standard formula of expressing the equation of a line is;
y = mx + b where;
m is the slope
b is the y-intercept
Using the coordinate points (20,36) and (4, 12)
Get the slope:
[tex]Slope = \frac{12-36}{4-20}\\Slope = \frac{-24}{-16}\\Slope=\frac{3}2}=1.5[/tex]
The point where the line meets the y-axis is the t intercept. From the graph, the y-intercept is b = 6
Get the required equation:
[tex]y=mx+b\\y=1.5x + 6[/tex]
Hence the required for the linear model in the scatter plot is y = 1.5x + 6

Spencer has a rectangular garden. The length and width are both odd numbers and the perimeter is 16 feet. What can be the area of his garden? Find all possible answers.
Area of rectangle = length x width
Perimeter of rectangle = 2 x (length + width)
Now we know that perimeter of rectangle = 16
2(length + width) = 16
Length + width = 16/2
Length + width = 8
Now the value of length and width is that if we add both values we have the answer 8.
So, here are some possible values of length and width and also that length and width are odd numbers;
Odd numbers are = 1,3,5,7,….
7 + 1 = 8
5 + 3 = 8
So, either length is 7 and with is 1 or length is 5 and width is 3
So area of rectangle = 7 x 1 = 7 or 5 x 3 = 15
Thus, the possible values of area of rectangle are 7 ft² and 15 ft².

It tries to explain natural phenomena by analyzing, observing, and testing.
The answer is (C.) It ignores parts of the method within an investigation.
What is pseudoscience?Pseudoscience is a proposition, a finding, or a system of explanation that is presented as science but that lacks the rigor essential to the scientific method. Pseudoscience can also be the result of research that is based on faulty premises, a flawed experimental design, or bad data.
Among the most notable developments in the history of pseudoscience in the 19th century is the rise of Spiritualism (traced in America to 1848), homeopathy (first formulated in 1796), and phrenology (developed around 1800).

David cycles x km in 3 hours. if he maintains the same average speed, how far can he cycle in 12y minutes
David can cycle [tex]\( \frac{xy}{15} \)[/tex] kilometers in 12y minutes if he maintains the same average speed.
To find out how far David can cycle in 12y minutes, we first need to convert the time from minutes to hours, since David's speed is given in kilometers per hour.
Since there are 60 minutes in an hour, we can convert 12y minutes to hours by dividing by 60:
[tex]\[ \text{12y minutes} = \frac{12y}{60} = \frac{y}{5} \text{ hours} \][/tex]
Now, we know that David cycles x kilometers in 3 hours, so we can find his average speed:
[tex]\[ \text{Average speed} = \frac{\text{Distance}}{\text{Time}} \]\[ \text{Average speed} = \frac{x \text{ km}}{3 \text{ hours}} \][/tex]
Now, using the average speed, we can find the distance David can cycle in [tex]\( \frac{y}{5} \)[/tex] hours:
[tex]\[ \text{Distance} = \text{Average speed} \times \text{Time} \]\[ \text{Distance} = \left( \frac{x}{3} \right) \times \left( \frac{y}{5} \right) \]\[ \text{Distance} = \frac{xy}{15} \][/tex]

Mr. Rose spent $63 for a sport jacket and a pair of slacks. If the jacket cost $33 more than the slacks, how much did he pay for each?
Which system of equations represents the word problem if j is the jacket price and s is the price of the slacks?
j + s = 63 and s - j = 33
j + s = 63 and j - s = 33
js = 63 andj/s = 33
Answer:
The system of the equations is: j+s=63 and j-s=33
The Jackets price is j=48
The slacks prices is s=15
Step-by-step explanation:
You know for the problem that:
j+s=65
And
j= s+33; from this equation you get j-s=33
Then you replace j "j=s+33" in the first equation:
(s+33)+s=63
2s+33=63
2s=63-33
s=(63-33)/2
s=15
and you know that: j=s+33
Then, j=15+33=48
and j+s=63
48+15=63
Ian wants to promote his band on the internet. Site a offers website hosting for $4.95 per month with a $49.99 startup fee. Site b offers website hosting for $9.95 per month with no startup fee. Write and solve an inequality to determine how many months lan could have his wedsite on site b and still keep his total cost less than site a
Ian could have his website on site B for less than 10 months for it to be cheaper than hosting on site A.
Explanation:To solve this question, we need to find when the costs between site a and site b equal each other. Since site a charges $4.95 per month plus a $49.99 startup fee, the cost of site a can be modelled by the equation: 4.95x + 49.99. Site b charges $9.95 per month with no startup fee, so its cost can be modelled by the equation 9.95x. We can now set up the inequality as follows:
4.95x + 49.99 > 9.95x
To solve for x, we will subtract 4.95x from both sides of the inequality, getting 49.99 > 5x. Finally, we divide each side by 5 to solve for x, resulting in x < 10. So Ian could have his website on site b for less than 10 months and still keep his total cost less than site a.

The domain of a radical function is the set of all x for which the radicand is positive. True or false?
The domain of a radical function is the set of all x for which the radicand is positive.
Explanation:The statement in the question is almost correct. The domain of a radical function is the set of all x for which the radicand is non-negative, not just positive.
A radical function is defined as a function that contains a radical expression, which is the square root or any higher-order root of a variable or expression. The domain of a radical function is the set of all values of x that make the radicand, which is the expression inside the radical, positive.
For example, let's consider the function f(x) = √(x+3). The radicand x+3 can only be positive for values of x greater than -3. Therefore, the domain of this function is (-3, ∞).

A meteor crater is 3300 feet in diameter. Approximate the distance around the crater. Use 3.14 for pie.
circumference = diameter x PI
3300 *3.14 = 10,362 feet
Answer:
Distance around the crater is 10362 feet.
Step-by-step explanation:
Given : A meteor crater is 3300 feet in diameter.
To find : Approximate the distance around the crater. Use 3.14 for pie.
Solution: We have given Diameter = 3300 feet.
Radius = [tex]\frac{Diameter}{2}[/tex].
Radius = [tex]\frac{3300}{2}[/tex].
Radius = 1650 feet.
Circumference = 2 * pi* radius.
Circumference = 2 *3.14* 1650.
Circumference = 3.14 * 3300.
Circumference = 10362 feet.
Therefore, Distance around the crater is 10362 feet.
