What must be added to X² 4x+?

Answer: The perimeter of a rectangle is the sum of the lengths of its four sides which is given by the expression: P = 2l + 2w (where l is the length and w is the width)

The expression that does not show this relationship is P = l + w

It doesn't show the relationship because it doesn't take into account the two sides that are equal to the width and the two sides that are equal to the length.

P = 2l + 2w shows the relationship as it considers both length and width of the rectangle twice, once for each pair of sides.

Answer:

56.8x+39.2 Welcome :D

Step-by-step explanation:

Answer:

[tex]56.8x+39.2[/tex]

Step-by-step explanation:

First, you must distribute the 2's to the expressions:

2(4.4x+7.6) = 2(4.4x) + 2(7.6) which is equal to 8.8x + 15.2 and;

2(24x+12) = 2(24x) + 2(12) = 48x + 24

Now add both: 8.8x + 48x + 24 + 15.2 ; combine like terms.

56.8x + 39.2 is what you get from doing that.

This cannot be simplified any further, and therefore is your answer:

56.8x + 39.2

An equation that has one solution for y for each value of x is referred to be a function. A function pairs each input of a particular type with exactly one output.

The subject of mathematics includes quantities and their variations, equations and related structures, forms and their locations, and places where they can be found. The term "function" refers to the relationship between a set of inputs, each of which has an associated output. A relationship between inputs and outputs in which each input leads to a single, distinct result is known as a function.  Usually, f is used to denote functions (x). input is an x. There are four main types of functions accessible. based on the following factors: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

To determine if the set of ordered pairs satisfies an exponential function, x -coordinates must have a constant increment.

We know that generally exponential function is written in the form function can be written in the form y = ab^x ,

where a and b are real numbers such that, a ≠ 0 , b > 0 , and b ≠ 1

a is called the initial value of function

and b is the constant ratio

We know that as x increases by a constant value, the value of y increases by a common ratio. This is characteristic of all exponential functions.

To determine whether the set of ordered pairs satisfies an exponential function, the condition that 'The x -coordinates must have a constant increment' must be satisfied.

The rider has 141 laps left to finish the race.

If a rider has already cycled 4.75 km, and each lap measures 0.25 km, we can determine how many laps the rider has completed by dividing the distance already cycled by the distance per lap.

To find out how many laps the rider has left to finish the race, we will use the information on the total number of laps to complete the race: 160 laps.

The rider has completed:

4.75 km / 0.25 km = 19 laps

The rider has yet to finish:

160 laps - 19 laps = 141 laps

So the rider has 141 laps left to finish the race.

Therefore, the rider has 141 laps left to finish the race.

The polynomial h(x)=x^4+2x^3-13x^2-14x+24 in the factored form is (x−1)(x+2)(x−3)(x+4). The real roots of the polynomial is x= 1, x = 3, x = -2, x  = -4.

What is a polynomial function?

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable.

The polynomial function is -

h(x)=x^4+2x^3-13x^2-14x+24

Divide the polynomial h(x) by (x-1) -

(x^4+2x^3−13x^2−14^x+24)=(x−1)(x3+3x2−10x−24)

Divide (x^3+3x^2−10x−24) by (x+2) -

(x−1)(x^3+3x^2−10x−24)=(x−1)(x+2)(x^2+x−12)

Solve the quadratic equation x^2+x−12=0.

x^2+x−12=0

x^2+4x-3x-12=0

x(x+4)-3(x+4)=0

(x+4)(x-3)=0

So, (x−1)(x+2)(x^2+x−12)=(x−1)(x+2)(x−3)(x+4)

Therefore, x^4+2x^3−13x^2−14x+24=(x−3)(x−1)(x+2)(x+4) .

The Rational Root Theorem tells us that if the polynomial has a rational zero then it must be a fraction q/p, where p is a factor of the constant term and q is a factor of the leading coefficient.

We can see that p(1)=0 so x=1 is a root of a polynomial h(x).

Divide the polynomial by (x-1) -

(x^4+2x^3−13x^2−14x+24)/(x-1)=(x^3+3x^2−10x−24)

Divide (x^3+3x^2−10x−24) by (x-3) -

(x^3+3x^2−10x−24)/(x-3) = (x^2+6x+8)

To find the last zero, solve equation x+4=0

x=-4

Therefore, the real roots are - x = 1, 3, -2, -4.

All of the matching angles and lengths in related shapes are equal and in the same ratio.

If two figures share the same shape, congruent corresponding angles (which means the angles in the same places of each shape are the same), and identical scale factors, they are said to be "similar figures."

Given that rectangle EFGH is similar to rectangle JKLM, it means the corresponding sides of both rectangles are similar, and as such the ratios if the corresponding sides of rectangle EFGH and rectangle JKLM would be equal.

Thus, EF/JK = FG/KL

Let represent the amount the first fund get by x and the amount the second fund get by y.

Therefore x+y = 1600 equation 1

and 9/100 × x + 4/100 × y = 84

9x/100 + 4x/100 = 84

multiply through by 100

9x + 4x = 8400 equation 2

9x+ 9y = 14400 equation 3

9x + 4y = 8400 equation 4

subtract equation 4 from 3

5y = 6000

y = 6000/5

y = $1200

On solving the question, unit rate by using the given graph could be 2.4 potatoes/pound

Graph can be defined as the visual representation which is used to represent the data.

The unit rate is the slope of the line.

= (36 potatoes - 12 potatoes)/(15 pounds - 5 pounds)

= (24potatoes)/(10 pounds)

= 2.4 potatoes/pound

The relationship here is proportional, so the line goes through the point (0, 0) and the unit rate can be figured from any point:

(12 potates)/(5 pounds)

Due to the corresponding angle property, which requires that the sum of neighboring opposite angles be 180, the angles are 90 and 79.8.

In Euclidean geometry, an angle is a shape that is made up of two rays, known as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are positioned. When two planes collide, an angle is also created. They are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two rays or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, also known as the sides of the angle, converge.

What is linear inequality?

A linear inequality is a mathematical statement that describes a relationship between two or more variables that form a half-plane when graphed. The equation of a linear inequality is in the form of "ax + by < c" or "ax + by > c" or "ax + by <= c" or "ax + by >= c", where x and y are variables, and a, b and c are constants.

An inequality that could be used to determine the minimum number of gallons, g, of gasoline Darla would need to drive 120 miles to her brother's house is:

g >= 120/37.5

This inequality states that the number of gallons, g, must be greater than or equal to the number of miles Darla needs to drive, 120, divided by the number of miles per gallon her car gets, 37.5. This is because Darla wants to ensure that she has enough gasoline to make the trip, and she may not want to risk running out of gas on the way.

Another way to write this inequality is

g * 37.5 >= 120

This inequality represents the same meaning as before, we multiply g by the number of miles per gallon the car gets, 37.5 and it should be greater than or equal to the distance she needs to travel which is 120 miles.
