the length of a rectangle is 6 feet longer than the width. the perimeter is 28 feet. find the dimensions of the regtangle
Answers
The length of rectangle :10 feet
The width of rectangle : 4 feet
Given
perimeter of the rectangle :28 feet
let width of the rectangle be :x
and length of the rectangle be : 6+x (as per given condition)
therefore
perimeter = 2(length +width)
28 = 2(6+x+x)
28 = 2(6+2x)
28 = 12+4x
28-12 = 4x
16 = 4x
x = 4
as width of rectangle is : 4
similarly length : 6+x
6+4
:10
The dimensions of the rectangle are : length =10
width = 4
verification :
perimeter =2(l+w)
28 = 2(10+4)
28 = 28

The height that Plant A has grown taller, as regards Plant B, is D. 1 / 2 inch
How to find the height difference ?The height of Plant A is 5 / 6 inches while the height of plant B is 1 / 3 inches. To find how much taller Plant A is than Plant B, you need to subtract the height of Plant B from the height of Plant A.
As these fractions have different denominators, you need to find a common denominator of the bases. This common denominator would be the least common multiple of the denominators of 3 and 6.
This least common multiple is 6. Then divide the common denominator by the denominator of the height and multiply it by the numerator to give ;
= ( 5 - 2 ) / 6
= 3 / 6 inches difference
In the simplest form, this is:

What is an equation that passes through the points (-6,1) and (6,7)
Answers
Considering the expression of a line, the equation of the line that passes through the points (-6,1) and (6,7) is y=1/2x +4.
What is a linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin.Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope can be calculated using:
m= (y₂ - y₁)÷ (x₂ - x₁)
Substituting the value of the slope and the value of one of the points in y= mx + b, the value of the ordinate to the origin b can be calculated.
Equation in this caseIn this case, being (x₁, y₁)= (-6, 1) and (x₂, y₂)= (6,7), the slope can be calculated as:
m= (7 -1)÷ (6 -(-6))
m= (7 -1)÷ (6 +6)
m= 6÷ 12
m= 1/2
Considering point 2 and the slope m, you obtain:

In this case, we are given 4 options:
Loan L has a nominal rate of 8.254% compounded dailyLoan M has a nominal rate of 8.474% compounded weeklyLoan N has a nominal rate of 8.533% compounded monthlyLoan O has a nominal rate of 8.604% compounded yearlyThe formula of compounded interest rate is:
[tex]A = P (1+\frac{r}{n})^{nt}[/tex]
Where:
A = amount, P = principal amount, r = interest rate, n = number of times interest rate compounded, t = time
Let’s assume the principal amount is $100 for 1 year
Loan L =
[tex]A = 100 (1+\frac{0.08254}{356})^{356x1}[/tex]
A = $108.603
Loan M =

2. To calculate the average, add the three values together and divide by three.
3. The formula for a triangular method is therefore (x1 + x2 + x3) / 3.
The triangular method is a method used to calculate an average of three different values. This method is most useful when there is not enough information available to calculate a more accurate average. To calculate an average using the triangular method, the three values (x1, x2, and x3) are added together and then divided by three. The formula for a triangular method is (x1 + x2 + x3) / 3. This method is useful for finding an average when a more accurate average cannot be calculated due to a lack of data. It is also used when data points are not necessarily related, as the triangular method is less affected by outliers than other methods of calculating an average. The triangular method is a quick and easy way to find an average when more complex calculations are not possible.

[tex]\mathrm{Factoring}\:4x^3-15x^2-31x+30:\quad \boxed{\left(x+2\right)\left(4x-3\right)\left(x-5\right)}[/tex]
Step-by-step explanation:
This is a particularly tough question. It involves polynomial division(a real laborious process) and solving using quadratic formula.
I presume your school has provided you the resources for both.
Anyways, here goes a brief explanation
To find the roots(zeros) of a polynomial, [tex]f(x)[/tex] , set [tex]f(x) = 0[/tex] and solve for values of [tex]x[/tex]
In general, if [tex]a[/tex] is a zero of [tex]f(x)[/tex], then [tex]f(x) \div(x-a)[/tex] will leave no remainder. In other words, it is a factor of the polynomial. It also means [tex]x - a = 0[/tex]
The given polynomial is [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex]
We are given that [tex]- 2[/tex] is a zero of [tex]f(x)[/tex]. This simply means that [tex]f(-2) = 0[/tex]
Plugging [tex]-2[/tex] into the function gives
[tex]f(-2) = 4(-2)^3 -15(-2)^2 - 31x + 30\\\\ = 0 =4\left(-8\right)-15\cdot \:4-31\left(-2\right)+30[/tex]
Which indeed is 0
Here [tex]a = -2[/tex] , so [tex]x - (-2)[/tex] which is [tex]x + 2[/tex] is a factor of[tex]f(x)[/tex]. It also means that
[tex]x-(-2) = 0 \;or\; x + 2 = 0[/tex]
Steps to factor the polynomial [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex] :
Divide [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex] by [tex]x+2[/tex][tex]\dfrac{4 x^{3} - 15 x^{2} - 31 x + 30}{x + 2} = 4x^2-23x\:+\:15[/tex]The quotient is a quadratic equation which can be solved using the quadratic formula available in most scientific calculators
The roots of this quadratic equation are
[tex]x=5,\:x=\dfrac{3}{4}[/tex]
This means [tex]x - 5[/tex] is one factor and
[tex]x - \dfrac{3}{4}[/tex]
is another factor
Since [tex]\dfrac{3}{4}[/tex] is a zero, [tex]x - \dfrac{3}{4} = 0[/tex]
Multiplying both sides of the above by [tex]4[/tex] gives [tex]4x -3 = 0.[/tex] So [tex]4x-3[/tex] is the third factor, replacing [tex]x - \dfrac{3}{4}[/tex]
The factors of [tex]4 x^{3} - 15 x^{2} - 31 x + 30[/tex]
are:
[tex]x+2, x-5 \;and \;4x-3[/tex]

Answers
So, the correct answer is (d) 150 mi.
To find out how far Greg drove, you need to multiply the speed of his car (50 mph) by the amount of time he spent driving (212 hours).
Speed = Distance/Time
Distance = Speed * Time
Distance = 50 * 212
Distance = 10600 miles
So, Greg drove 10600 miles.
It's important to note that the question is asking for the answer in miles and not kilometers.
To convert meters to miles, you can use the conversion factor 1 mile = 1609.344 meters.
To convert a measurement in meters to miles, you can multiply the number of meters by the conversion factor.
For example, if you want to convert 1000 meters to miles, you would multiply 1000 by the conversion factor of 1/1609.344 which is approximately 0.000621371.

The number of positive zeros is of 4, while the number of negative roots is of zero.
How to obtain the number of positive and negative roots?The number of possible positive and negative roots is obtained using Descartes' Rule.
The Descartes' Rule states that the number of positive roots is at most the number of sign changes in the sequence of polynomial's coefficients (disconsidering the zero coefficients), while the difference between these two numbers is always even.
The number of changes for this problem is given as follows:
4 changes.
The changes are given as follows:
x^4 to x^3.x^3 to x^2.x^2 to x.x to constant.As there are 4 changes, the number of positive roots is of 4, while the number of negative roots is of zero, as the polynomial is of the fourth degree.
Missing InformationThe answer was given in general terms, as the statements are not presented.
