Answer:

Step 1

Step-by-step explanation:

They're all wrong expansions but step 1 was where he made his first error... He shifted the bracket putting 3x inside the bracket... While the other steps the first expansion of 3x eliminating the bracket was correct.

The correct expansion is meant to be 3x + 21 + 5 = 3x + 26

Answer:

12.56

Step-by-step explanation:

the equation for a circumference is C=2pi r

C=2*3.14*2

2*3.14=6.28

6.28*2=12.56

1.3 × 10^6 - 0.68 × 10^6 =

( 1.3 - 0.68 ) × 10^6 =

0.62 × 10^6 =

6.2 × 10^5

Answer:

a= 1/(a-5) then a2-1/A2 = 5√29

Step-by-step explanation:

Area = ( 4 + 14 ) × 10 / 2 + 1/2 × 14 × 8

Area = 180/2 + 7 × 8

Area = 90 + 56

Area = 146 cm^2

Answer:

x = -2, y = -8

Step-by-step explanation:

13(y + 6) - 6y = 22

=> 13y + 78 - 6y = 22

=> 7y = -56

=> y = -8

x = -8 + 6

=> x = -2

Answer:

55 centimeters

Step-by-step explanation:

It is a right triangle which means it will add up to 90 degrees. You would start by adding 20 and 15 which is 35 and then subtract 35 from 90 to get 55. I hope this helped :)

Answer:

A is the truth

One trick that helps me memorize the placement of the atoms in each state is how the state acts. For example)

Solid, looks tough rigid. A group of Knight made a strong SOLID barrier by grouping together. So you assume that Solid has atoms that are close together

so knight (atoms) together = solid

Liquid, look at how wobbly it is, the knights are running together so their shield is NO LONGER SOLID. You assume that it is liquid cause they are all around, yet they are still together.

so knight (atoms) all around the place together = liquid

Now gases, they are crazy, they go everywhere. The knights are running their own separate way.

So knights (atoms) running everywhere = gases

Hope that answers your question.

Wish the examples were written better tho.

Step-by-step explanation:

Respuesta:

h = V / 15

Explicación paso a paso:

El volumen de un prisma rectangular se calcula usando la relación:

Largo ancho alto

Donde, largo y ancho son la dimensión de la base

Por eso,

Volumen = Base * altura

Volumen = (5 cm * 3 cm) * altura

De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h

V = 15h

Divide ambos lados entre 15

V / 15 = 15h / 15

V / 15 = h

Answer: A Diameter x pi= circumference

Step-by-step explanation:

The circumference of a circle is given as:

= 2πr

where,

π = pi = 3.14

r = radius

Note that diameter = 2 × radius.

Therefore, circumference = 2πr = πd

Therefore, circumference will be pi multiplied by diameter. The correct option is A.

The correct statement is:

A. Diameter x pi = circumference

Answer:

(0, -2)

Step-by-step explanation:

The x- and y-coordinates indicate the position of a point in the 2D coordinate plane relative to the origin. The coordinates are written as an ordered pair of numbers (x, y), where x indicates horizontal position and y indicates vertical position.

Example

The position of the point in the figure below is specified by the ordered pair, (6, 4). 6 is the x-coordinate and 4 is the y-coordinate of the point.

Answer:

the second box for y is 9

the third box for x is 2.5

im not sure about the third box for y

As per the given question, it is stated that the length of a rectangle is 5 m less than twice the breadth.

Assumption : Let us assume the length as "l" and width as "b". So,

[tex] \twoheadrightarrow \quad\sf{ Length =2(Width)-5} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]

Also, we are given that the perimeter of the rectangle is 50 m. Basically, we need to apply here the formula of perimeter of rectangle which will act as a linear equation here.

[tex]\\ \twoheadrightarrow \quad\sf{ Perimeter_{(Rectangle)} = 2(\ell +b) } \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 2(2b-5+b)} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 2(3b-5)} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50= 6b - 10} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{50+10= 6b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{60= 6b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\sf{\cancel{\dfrac{60}{6}}=b} \\[/tex]

[tex]\\ \twoheadrightarrow \quad\underline{\bf{10\; m = Width }} \\[/tex]

Now, finding the length. According to the question,

[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=2(10)-5\; m} [/tex]

[tex] \twoheadrightarrow \quad\sf{ \ell=20-5\; m} [/tex]

[tex]\\ \twoheadrightarrow \quad\underline{\bf{15\; m = Length }} \\[/tex]

Therefore, length and breadth of the rectangle is 15 m and 10 m.

Answer:

x = 5

Step-by-step explanation:

TU is a tangent segment with length 6.  RT is a secant segment.

In the circle, the square of the tangent is equal to the product (multiply) of the part of the secant outside the circle and the secant's entire length.

Words don't work well here, do they!

In symbols,  (ST)(RT) = (TU)^2
