The rectangle shown has a perimeter of 104 cm and the given area. Its length is 8
more than three times its width. Write and solve a system of equations to find the
dimensions of the rectangle.
Therefore , the solution is l=3 w + 8 is the formula to solve for the dimensions of a rectangle.
Rectangle: What is it?
In Euclidean plane geometry, a rectangle is a square with four right angles. You may also refer to it as a quadrilateral that seems to be equiangular, meaning that each of its angles is equal. Another possibility for the parallelogram is a straight angle. Four of the sides of a square are of identical length. Four 90 ° vertices and equal equal sides make up a rectangle-shaped quadrilateral.
Here,
Given that the rectangle's perimeter is 104 cm
W = the rectangle's width
rectangle's length is equal to 3 w + 8.
Rectangle perimeter equals 2 (length + width).
= >104 =2(3 w + 8 + w)
= >104 =2(4 w + 8)
= >104 =8 w + 16
= >8 w = 104- 16
= >8w = 88
= >w = 11
hence the rectangle's length is equal to 3 w plus 8.
= >3 * 11 + 8
=> 33 + 8
=> 41
Consequently, l=3 w + 8 is the formula to solve for the dimensions of a rectangle.

It rains an inch and a half in 8 hours. If it rains at the same rate the rest of the day, how much more will it rain? ____inches
(Please explain how you got your answer)
Answer: Yoo
To find out how much more it will rain, we can use the information given to calculate the rate of rain in inches per hour. We know that it rained an inch and a half in 8 hours, so the rate of rain is:
(1.5 inches) / (8 hours) = 0.1875 inches/hour
Now that we know the rate of rain, we can use it to find out how much more it will rain in the rest of the day. We can assume that the rest of the day has 16 hours, so we can use the rate of rain to find out how much more it will rain:
(0.1875 inches/hour) x (16 hours) = 3 inches
So, it will rain 3 inches more the rest of the day.
We can also check this by multiplying the inches per hour (1.5/8) by the number of hours in a day (24) and subtracting the inches of rain fallen (1.5 inches)
(1.5/8)*24-1.5 = 3
This means that it will rain 3 inches more the rest of the day.

Which statement could describe the returns from a bond?
Answer:
A bond is a debt security, meaning that it represents a loan made by an investor to a borrower (typically a corporation or government). The bond issuer promises to pay interest to the bondholder, usually at regular intervals, and to repay the principal when the bond matures.
So, a statement that could describe the returns from a bond is:
"Bonds typically provide a steady stream of income in the form of interest payments, but the return on investment is generally lower than that of stocks."
Another statement that could describe the returns from a bond is:
"Bonds are considered to be a relatively safe investment option, but they are not as profitable as stocks in terms of returns."
In general, bonds are considered to be less risky than stocks, but they also typically offer lower returns.

How long will it take a bus travel 72 km HR to go 36 km?
It will take the bus one hour to travel 36 km at a rate of 72 km per hour.
Calculate the rate of speed: 72 km/hr
Calculate the time it will take to travel 36 km: 36 km/72 km/hr = 0.5 hr
Convert 0.5 hr to minutes: 0.5 hr x 60 min/1 hr = 30 min
Add the time in minutes to the hour: 60 min + 30 min = 90 min
Convert 90 min to hours: 90 min/60 min/hr = 1.5 hr
Round the time to the nearest hour: 1.5 hr = 1 hr
The amount of time it will take a bus to travel 36 km at a rate of 72 km/hr can be calculated by dividing the distance (36 km) by the rate of speed (72 km/hr). This yields 0.5 hr. Since time is measured in minutes, 0.5 hr can be converted to 30 min. Adding the time in minutes (30 min) to the hour (60 min) yields 90 min. This can then be converted to 1.5 hr. To get an answer in hours, the time must be rounded to the nearest hour, which gives 1 hr. Therefore, it should take the bus one hour to travel 36 km at a rate of 72 km/hr.

How do you find the range of K in a quadratic equation?
The range of K in a quadratic equation is the set of all possible values that K can take on in order for the equation to remain valid.
What is quadratic equation?A quadratic equation is an algebraic equation that contains a second-degree polynomial with one or more unknown variables. It can be written in the form of ax2 + bx + c = 0, where a, b, and c are just numbers, and x is the unknown variable. The solutions to the equation can be found using the quadratic formula. Quadratic equations are used to model a variety of different problems in mathematics, physics, and engineering.
To find the range of K, we must first understand the quadratic equation. A quadratic equation is an equation in which a variable (K) is raised to the second power and is equal to some other constant. The most common form of a quadratic equation is:
K2 = C
Where K is a variable, and C is a constant. The range of K in a quadratic equation can be found by forming two equations – one equation with K2 = C, and the other equation with K2 = -C.
The first equation (K2 = C) will tell us the maximum value that K can take on. To find this value, we take the square root of C and assign that value to K. The maximum value of K is the square root of C.
The second equation (K2 = -C) will tell us the minimum value that K can take on. To find this value, we take the square root of -C and assign that value to K. The minimum value of K is the negative square root of C.
Therefore, the range of K in a quadratic equation can be found by calculating the square root of C and the negative square root of C. The range of K is the set of all possible values that K can take on in order for the equation to remain valid, which is between the maximum and minimum values found.

Is the binomial 7x+1 equal to the trinomial 3x2−2x+1?
Is the trinomial −2x2+5x+6 equal to the binomial 4x2+5x?
a) The values of x for which trinomial x² −11x + 31 equal to 1 are (11 ± 3i)/2.
b) The values of x for which the polynomials x² − 5x− 3 and 2x − 5 are equal are (7 ± √41)/2.
c) The values of x for which the binomial 7x+1 equal to the trinomial 3x² - 2x + 1 are
x = 0, 1/3.
d) The values of x for which the trinomial −2x² + 5x + 6 equal to the binomial 4x² + 5x are ± √3.
In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves arithmetic options and non-negative integer exponentiation of variables.
Monomial : is the algebraic expressions with one term or like terms, so “Mono”mial. For example, 2x + 5x + 12x = 19x is a monomial.Binomial: is the algebraic expressions with two like terms, so “Bi”nomial. For example, 2x + 7x² is a monomial.Trinomial: is the algebraic expressions with three like terms, so “Tri”nomial. For example, x + 5x² + 10x³ is a monomial.Now, see the problem, we have to determine the value of x in each case.
a) The trinomial x² - 11x + 31 equal to 1
=> x² - 11x + 31 = 1
Using the quadratic formula,
=> x = ( -(-11)± √121 - 124)/2
=> x = ( 11 ± √-3 )/2 = (11 ± 3i)/2
So, required value of x is (11 ± 3i)/2.
b) The values of the polynomials x² − 5x− 3 and 2x − 5 equal.
=> x² − 5x− 3 = 2x − 5
=>x²− 5x− 3 - 2x + 5 = 0
=> x² - 7x + 2 = 0
=> x = (-(-7) ± √49 - 8)/2
=> x = (7 ± √41)/2
c) The binomial 7x+1 equal to the trinomial 3x² - 2x + 1
=> 7x + 1 = 3x² - 2x + 1
=> 3x² - 2x + 1 - 7x - 1 = 0
=> 3x² - 9x = 0
=> x( 3x - 9 ) = 0
=> x = 0, 1/3
d) The trinomial −2x² + 5x + 6 equal to the binomial 4x² + 5x.
=> 2x² + 5x + 6 = 4x² + 5x
=> 2x² + 5x + 6 - 4x² - 5x = 0
=> - 2x² + 6 = 0
=> 2x² -6 = 0
=> x² = 6/2 = 3
=> x = ± √3
Hence, the required values of x are ±√3.

Is this parabola a function?
Yes, a parabola is always a function, specifically a quadratic function.
To determine if a parabola is a function, you will need to check if it passes the vertical line test.
To do this, draw a vertical line through any point on the parabola and see if it intersects the parabola more than once. If it does, then the parabola is not a function. If it only intersects the parabola once, then the parabola is a function. To graph a parabola, you will need to find five points that make up the curve in order to get a better approximation of the general shape. This can be done by using the equation of the parabola in the form y = ax2 + bx + c . First, calculate the x-intercepts by setting y = 0 and solving for x. Then, calculate the y-intercept by setting x = 0 and solving for y. Finally, calculate two more points by solving for x when y is equal to a positive and negative value.
