3 - 2(x +3) = x - 18 ?

Answer:

A) 2(x-3)(x-5)

Step-by-step explanation:

2x^2-16x+30

2(x^2-8x+15)

2(x-3)(x-5)

The factors for the given trinomial is 2(x-6)(x-5)

A trinomial is an algebraic expression that has three non-zero terms and has more than one variable in the expression.

Given is a trinomial, 2x²-16x+30

On factorizing,

= 2x²-16x+30

= 2x²-10x-6x+30

= 2x(x-5)-6(x-5)

= (2x-6)(x-5)

= 2(x-6)(x-5)

Hence, the factors for the given trinomial is 2(x-6)(x-5)

Answer:

The answer is "bulb, expands, and glass ".

Step-by-step explanation:

The bulb thermometer is the common glass temperature sensor for which you might be grown up. This thermometer is filled with a liquid, typically mercury. Bulb thermometers work on the simple premise that it volume of the liquid varies in proportion to its volume.

It is a glass tube that is pre full with a fluid such as a hydrogen or liquor and is sealed at both sides. The fluid in the glass tube rises as the mercury inside the thermometer's bulb increases. When the temperature gauge is warm, the liquid inside flows up in the tube.

Answer:

Step-by-step explanation:

The first one

A sequence can be arithmetic, geometric, and it can take several other forms such as Fibonacci.

The given parameters are;

[tex]\mathbf{f(n) = f(n-1)-f(n-2)}[/tex]

[tex]\mathbf{f(1) = 2 }[/tex]

[tex]\mathbf{f(2) = 5 }[/tex]

Calculate f(3), f(4), f(5), f(6), f(7), and f(8).

Substitute 3 for n in [tex]\mathbf{f(n) = f(n-1)-f(n-2)}[/tex]

[tex]\mathbf{f(3) = f(3-1)-f(3-2)}[/tex]

[tex]\mathbf{f(3) = f(2)-f(1)}[/tex]

[tex]\mathbf{f(3) = 5-2}[/tex]

[tex]\mathbf{f(3) = 3}[/tex]

Following the above sequence, we have:

[tex]\mathbf{f(4) = f(3)-f(2)}[/tex]

[tex]\mathbf{f(4) = 3-5}[/tex]

[tex]\mathbf{f(4) = -2}[/tex]

[tex]\mathbf{f(5) = f(4)-f(3)}[/tex]

[tex]\mathbf{f(5) =-2- 3}[/tex]

[tex]\mathbf{f(5) = -5}[/tex]

[tex]\mathbf{f(6) = f(5)-f(4)}[/tex]

[tex]\mathbf{f(6) =-5- -2}[/tex]

[tex]\mathbf{f(6) = -3}[/tex]

[tex]\mathbf{f(7) = f(6)-f(5)}[/tex]

[tex]\mathbf{f(7) =-3--5}[/tex]

[tex]\mathbf{f(7) = 2}[/tex]

[tex]\mathbf{f(8) = f(7)-f(6)}[/tex]

[tex]\mathbf{f(8) =2--3}[/tex]

[tex]\mathbf{f(8) = 5}[/tex]

Hence, the values of f(3), f(4), f(5), f(6), f(7), and f(8) are 3, -2, -5, -3, 2, 5

Then, determine the value of f(25). ​

In (1), we have:

[tex]\mathbf{f(3) = 3}[/tex]

[tex]\mathbf{f(4) = -2}[/tex]

[tex]\mathbf{f(5) = -5}[/tex]

[tex]\mathbf{f(6) = -3}[/tex]

[tex]\mathbf{f(7) = 2}[/tex]

[tex]\mathbf{f(8) = 5}[/tex]

This means that:

[tex]\mathbf{f(n) = -f(n-3i)}[/tex]

Where i is greater than 0

Substitute 25 for n

[tex]\mathbf{f(25) = -f(25-3i)}[/tex]

Let i = 7.

So, we have:

[tex]\mathbf{f(25) = -f(25-3 \times 7)}[/tex]

[tex]\mathbf{f(25) = -f(25-21)}[/tex]

[tex]\mathbf{f(25) = -f(4)}[/tex]

So, we have:

[tex]\mathbf{f(25) = -(-2)}[/tex]

[tex]\mathbf{f(25) = 2}[/tex]

Hence, the value of f(25) is 2

Answer:

80^2 + 150^2

6400 + 22500 = 28,900

Something squared will equal 28,900

170^2 = 28,900

170 is your answer!

The length of the hypotenuse of the right triangle with legs of 80 feet and 150 feet is 170 feet.

To find the length of the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

In this case, the legs of the triangle have lengths of 80 feet and 150 feet, so we can label them as follows:

Leg 1: a = 80 feet

Leg 2: b = 150 feet

We can then use the Pythagorean theorem to solve for the length of the hypotenuse, which we can label as c:

c² = a² + b²

Substituting in the values for a and b, we get:

c² = (80 feet)² + (150 feet)²

c² = 6,400 square feet + 22,500 square feet

c² = 28,900 square feet

c = √(28,900 square feet)

c = 170 feet

Therefore, the length of the hypotenuse of the right triangle with legs of 80 feet and 150 feet is 170 feet.

Answer:

D. x = 11/c

Step-by-step explanation:

you add 4 to both sides so you can make the x by itself.

we are left with cx = 11

you divide c to both sides

Final Answer: x = 11/c

Answer:

sides are of 16 in

Step-by-step explanation:

here's your solution

==> area of square = 256 in^2. [given]

==> side of square = 4x

==> area of square= side^2

==> 4x^2 = 256

==> 16x^2 = 256

==> x^2 = 256/16

==> x^2 = 16

==> x = √16

==> x = 4

==> x = 4

hence sides are of 16 in

We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.

The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.

The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.

The shape that has a rotational symmetry is option C, which is a parallelogram.
