Answer:

When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order. Notice that the congruent sides also line up within the congruence statement. One congruence statement can always be written six ways.

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)

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

Answer:

The correct answer is B. Manifest Destiny was the belief that the United States was meant to be extended to the Pacific Ocean.

Step-by-step explanation:

The ideology of Manifest Destiny, whose predominance in American politics occurred especially during the 1800s, established that the United States was a nation whose destiny was to expand the guidelines of Western civilization throughout the North American continent, from the shores of the Atlantic to the Pacific. Thus, this doctrine encouraged the United States to acquire territories to the west, such as the Louisiana Purchase or the War against Mexico.

Just took the quiz and would like to verify that B is the correct answer and I'm so tired hsdjfgj it's late, good night.

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.

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

Step-by-step explanation:

Given the parabolic equation is in the form of (y-k)²=4p(x-h), this is a horizontal parabola with a vertical directrix at x=h-p where (h,k) is the vertex and the focus is (h+p,k). Since p=2, then the directrix is x=3-2=1. The vertex would be (h+p,k) -> (3+2,2) -> (5,2). Refer to the graph.
