15,12,9 find the nth term

Answers

Answer 1
Series is 15, 12, 9…,
Difference between terms is 3
By Arithmetic progression

a_{n}=a_{1}+(n-1)d
a_n = the nᵗʰ term in the sequence
a_1 = the first term in the sequence
d = the common difference between terms

So nth term is a(n) = 15 + (n-1)*3
= 15+ 3n -3
= 12 + 3n

Answer:

100.8 cm

Step-by-step explanation:

Area of square= side * side

let,

side=x

Substitute values in above formula:

635 [tex]cm^{2}[/tex]=x*x

[tex]x^{2}[/tex]=635 [tex]cm^{2}[/tex]

Taking square root on both sides:

x=25.2cm

side=25.2cm

Now, Permiter=4* side

Perimeter=4*25.2cm

Perimeter=100.8 cm

IS 4 x + 8 − 6 x + 12 = 3 ( x + 7 ) − 5 x − 1 Infinitely Many or No Solution or One Solution

Answers

Answer:first one infinently

Step-by-step explanation:

The solution of the equation are:

1. 6(x-3)+4x=5(2x-4)-2 → No solution.

2. 2 − 6 − 3 = 5 − (4 + 2) → No solution.

3. 6(x - 2) + 8 = 3(2x - 4) → No solution.

4. 4x + 8 - 6x + 12 = 3(x + 7) - 5x - 1 → One solution.

1. 6(x-3)+4x=5(2x-4)-2

Step 1: Distribute the numbers outside the parentheses:

[tex]\(6x - 18 + 4x = 10x - 20 - 2\)[/tex]

Step 2: Combine like terms:

[tex]\(10x - 18 = 10x - 22\)[/tex]

Step 3: Isolate the variable on one side:

10x - 10x = -22 + 18

0 = -4

The equation 0 = -4 is not true.

It means that the variable x has canceled out, and both sides of the equation are not equal.

So, there is no solution for this equation.

2. 2 − 6 − 3 = 5 − (4 + 2)

Step 1: Perform operations inside parentheses and simplify:

2 - 6 - 3 = 5 - 6

Step 2: Continue simplifying:

-7 = -1

The equation -7 = -1 is not true.

So, there is no solution for this equation.

3. [tex]\(6(x - 2) + 8 = 3(2x - 4)\)[/tex]

Step 1: Distribute the numbers outside the parentheses:

[tex]\(6x - 12 + 8 = 6x - 12\)[/tex]

Step 2: Combine like terms:

6x - 4 = 6x - 12

Step 3: Isolate the variable on one side:

6x - 6x = -12 + 4

0 = -8

The equation 0 = -8 is not true.

So, there is no solution for this equation.

4. [tex]\(4x + 8 - 6x + 12 = 3(x + 7) - 5x - 1\)[/tex]

Step 1: Combine like terms on each side of the equation:

-2x + 20 = 3x + 20 - 1

Step 2: Continue simplifying:

-2x + 20 = 3x + 19

Step 3: Isolate the variable on one side:

-2x - 3x = 19 - 20

-5x = -1

Step 4: Solve for x:

[tex]\(x = \dfrac{-1}{-5} = \dfrac{1}{5}\)[/tex]

The equation  [tex]x = \dfrac{1}{5}[/tex] is true, which means that the variable x has a unique value that satisfies the equation.

So, there is one solution for this equation.

Answers

Answer:

the answer is x8

Step-by-step explanation:

the answer is x8

Answer:

y = -2x

Step-by-step explanation:

The appropriate "direct variation" rule (formula) is y = kx.

Since y = 4 when x = -2, 4 = k(-2), or k = -2

Then the specific formula relating x and y is y = -2x

Is 331 in the sequence below? 1, 7, 13, 19, 25. ..​

Answers

Answer:

yes

Step-by-step explanation:

1, 7, 13, 19, 25, ...

a = 1

common difference = d = 7 - 1 = 6

13 - 7 = 6

nth term is

a(n) = a + (n - 1)d

= 1 + (n - 1)6

= 1 + 6n - 6

= 6n - 5

6n - 5 = 331

6n = 331 + 5

6n = 336

n = 56

as n is an integer

331 is 56th term

what is the meaning for all these

base angles of an isosceles triangle
base of an isosceles triangle
congruent polygons
congruent triangles
corollary
hypotenuse
legs of a right triangle
legs of an isosceles triangle
vertex angle of an isosceles triangle

Answers

Answer:

The base angles of an isosceles triangle are the angles formed by the base and one leg of the triangle. The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.

In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base.

Two polygons are congruent if their corresponding sides and angles are congruent. Note: Two sides are congruent if they have the same length and angles are congruent if they have the same measure. Congruent polygons necessarily have to have the same shape and the same size.

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal. We can tell whether two triangles are congruent without testing all the sides and all the angles of the two triangles.

corollary is a proposition that follows from (and is often appended to) one already proved.

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

Legs of a Right Triangle. The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse. Sometimes it is required to solve a right triangle to find the length of one or both of the legs of the right triangle.

The equal sides of an isosceles triangle are known as the 'legs.' The third and unequal side of an isosceles triangle is known as the 'base. The angles situated opposite to the equal sides of an isosceles triangle are always equal.

Every triangle has 180 degrees. An isosceles triangle has one vertex angle and two congruent base angles. Thus, 65 is the base angle and 50 is the vertex angle.

Mandy walks 42 ft in 7 seconds. What
is her walking speed in yards per
minute?

Answers

Answer:

not the answer: I hope you do amazing!!

Answer:

120 Yards

Step-by-step explanation:

42 feet is equal to 14 yards.

So if 14 yards is walked in 7 seconds then 2 yards are walked in 1 second.

So if 2 yards are walked in 1 second and there are 60 seconds in a minute, then 120 yards are walked in one minute.

So the answer is 120 yards.
