Radical expression are expressions that contains square root. The value of x from the given radical expression is 3

Given the equation expressed as:

x = 2 + √x - 2

Subtract 2 from both sides

x - 2 = √x - 2

Square both sides

(x-2)^2 = x - 2

x - 2 = 1

x = 1 + 2

x = 3

Hence the value of x from the given radical expression is 3

Answer:

0.4x^3 - xy.

Step-by-step explanation:

2/7x(1.4x^2-3.5y)       Distributing the2/7x over the parentheses:

= 2/7 * 1.4 x^3 - 2/7 *3.5xy

= 0.4x^3 - xy

The expression 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

To write 2/7x(1.4x² - 3.5y) as a polynomial, we need to first simplify the expression inside the parentheses by distributing the 2/7x:

2/7x(1.4x² - 3.5y) = (2/7x)(1.4x²) - (2/7x)(3.5y)

Next, we can simplify each term by multiplying the coefficients:

2/7x(1.4x² - 3.5y) = (4/5)x³ - (10/7)xy

Thus, 2/7x(1.4x² - 3.5y) can be written as the polynomial (4/5)x³ - (10/7)xy.

Answer:

It is health.

Step-by-step explanation:

It says that "The larger the MAD, the greater variability there is in the data (the data is more spread out)." So History would actually be the most wrong one. Health is the lowest value so Health is correct.

Answer:

Health

Step-by-step explanation:

MAD = median absolute deviation

It measures how spread out a set of data is, and is less affected by extremely high or low values.

The bigger the variance, the more spread out the data points are.

The smaller the variance, the less spread out the data points are.

Therefore, the scores were closest together in Health, since this has the smallest MAD.

Answer:

(x + 2)(x + 8)

Step-by-step explanation:

x² + 10x + 16

consider the factors of the constant term (16) which sum to give the coefficient of the x- term.

the factors are + 2 and + 8 , since

+ 2 × + 8 = + 16 and + 2 + 8 = + 10 , then

x² + 10x + 16 = (x + 2)(x + 8) ← in factored form

so

180 = 75 + 50 + x

x = 180 - 75 - 50

x = 55°

Given system

Solve it by substitution

Find the value of x

Find the value of y

Answer:

x = 200

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}x-y=80\\\\\dfrac{3}{5}=\dfrac{y}{x} \end{cases}[/tex]

Rearrange the second equation to make y the subject by multiplying both sides by x:

[tex]\implies \dfrac{3}{5} \cdot x=\dfrac{y}{x} \cdot x[/tex]

[tex]\implies y=\dfrac{3}{5}x[/tex]

Substitute this into the first equation and solve for x:

[tex]\implies x-\left(\dfrac{3}{5}x\right)=80[/tex]

[tex]\implies \dfrac{2}{5}x=80[/tex]

[tex]\implies \dfrac{2}{5}x \cdot 5=80 \cdot 5[/tex]

[tex]\implies 2x=400[/tex]

[tex]\implies \dfrac{2x}{2}=\dfrac{400}{2}[/tex]

[tex]\implies x=200[/tex]

Therefore, the value of x is 200.

If you want to find the value of y, simply substitute the found value of x into the first equation and solve for y:

[tex]\implies 200-y=80[/tex]

[tex]\implies 200-y+y=80+y[/tex]

[tex]\implies 200=y+80[/tex]

[tex]\implies 200-80=y+80-80[/tex]

[tex]\implies 120=y[/tex]

[tex]\implies y=120[/tex]

Answer:D

Step-by-step explanation:

The slope of a line will be 1/6. Then the correct option is D.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Slope = (y₂ - y₁) / (x₂ - x₁)

The points are given below.

(-6,3) and (12,6)

(x₁, y₁) = (-6,3)

(x₂, y₂) = (12,6)

Then the slope of a line will be

Slope = (6 – 3) / (12 + 6)

Slope = 3 / 18

Slope = 1/6

Then the correct option is D.

The coordinate of the given figure is (5,5) (5,-3) and (-1, -3). The coordinates of the circumcenter of the triangle is (2,1).

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

We can see the given triangle.

The coordinates of A are (-1,-3).

The coordinates of B are (-1,-3).

The coordinates of C are(5,5).

We know that the circumcenter of a right triangle is the midpoint of the hypotenuse.

Mid-point of hypotenuse AC is given by

[tex]x = x_1 +x_2 / 2\\y = y_1 +y_2 / 2[/tex]

So, x =( -1 + 5)/2 = 2

y =( 5-3)/2 = 1

Hence, the circumcenter of the triangle is (2,1).

The equation represents the volume of the portable fuel tank in terms of width (w) is w³ + 34w² + 145w - 33488 = 0.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

A portable fuel tank used to transport gasoline is in the shape of a rectangular prism.

The tank is 5 feet longer than it is wide and 29 feet deeper than it is wide.

The volume of the tank is 33,488 cubic feet.

Let the width of the rectangular prism be w. Then we have

length = w + 5

height = w + 29

Then the volume is given as

Volume = l × w × h

33488 = (w + 5) (w) (w + 29)

Then we have

[tex]\begin{aligned} \rm w^3 + 5w^2 + 29w^2 + 145w &=33488 \\\\\rm w^3 + 34w^2 + 145w - 33488 &= 0\\\\\rm (w - 23)(2w+57)(2w + 57) &= 0\\\\\rm w &= 23, -28.5, -28.5 \end{aligned}[/tex]
