Answer 1

Answer:

x=14

Step-by-step explanation:

This shape is a pentagon, as it has 5 sides. The formula to find the sum of the interior angles of a polygon is:

(n-2)*180

In this case n represents the number of sides. We can plug 5 into the equation to get...

(5-2)*180=3*180=540

Since all sides are equal, all angles are equal too therefore one angle is equivalent to...

540/5=108

This means...

9x-18=108


Add 18 to both sides

9x-18+18=108+18

9x=126

Divide both sides by 9

x=14

Answer 2

Answer:

x = 14

Step-by-step explanation:

This is a pentagon and there are five sides in a pentagon. All of the sides degrees added together makes 540.

Since the angles are the same and the average angle of every pentagon is 108, then 9x - 18 = 108.

108 + 18 = 126

9x = 126

9x/9 = 126/9

x = 14

Find the area of the semicircle.
Either enter an exact answer in terms of 7 or use 3.14 for 7 and enter your answer as a decimal.

Answers

Answer:

56.52 units²

explanation:

We should know circle's area: πr²Then the semi circle shall have half area, so formula: (1/2)πr²

Steps:

Using the formula:

→ (1/2)πr²

→ (1/2)(3.14)(6)²

→ 56.52 units²

Solution:

Note that:

Area of circle: πr²Circle/2 = SemicircleArea of semicircle = πr²/2Radius = 6 units

Finding the area of the semicircle:

πr²/2=> 3.14 x 6 x 6/2=> 3.14 x 6 x 3=> 56.52 units²

We can conclude that the area of the semicircle is 56.52 units².

add basic numbers ↓

2y + 6y +5y +10y -8

final answer ↓

23y -8

Answer: 23y - 8

Explanation: The formula to find the perimeter of a quadrilateral which is a 4 sided figure is P = a + b + c + d.
So you input the side lengths of the quad into the letters.
6y + 10 + 5y - 7 + 2y - 9 + 10y - 2
You add all the constants and the like terms. So 6y + 5y + 2y + 10y - 2 is 23y + 10 - 7 - 11.
-7 - 11 is -18,
23y + 10 - 18
And finally 23y - 18.

The equation that describes the given situation and the number of packs required are; 25x = (17 * 10) and x = 7 packs

How to write algebraic equations?

We are told that;

Each sticker comes in a pack of 25

Now, she wants to give each of the 17 guests at least 10 stickers.

Let the number of packs she will require be x. Thus, the expression to describe this situation is;

25x = (17 * 10)

x = (17 * 10)/25

x = 6.8 packs

Approximating to a whole number gives us 7 packs of stickers required.

What is simplifying an algebraic expression?

Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.

[tex]= \frac{x+2}{x^{2} +5x+6} / \frac{3x+1}{x^{2} -9}\\ \\ = \frac{x+2}{x^{2} +5x+6} * \frac{x^{2} -9}{3x+1}[/tex]

Solving in parts,

[tex]=x^{2} +5x + 6\\\\= x^{2} + 2x + 3x + 6\\\\=x(x+2) + 3(x+2)\\\\=(x+2)(x+3)[/tex]

[tex]= x^{2} -9\\\\= x^{2} - 3^{2}\\ \\=(x - 3)(x + 3)[/tex]

[tex]= \frac{x+2}{x^{2} +5x+6} * \frac{x^{2} -9}{3x+1}\\\\= \frac{x+2}{(x+2)(x+3)} * \frac{(x+3)(x-3)}{3x+1}\\ \\=\frac{x-3}{3x + 1}[/tex]

Answer:

x = -3.5 or x = 1.7

Step-by-step explanation:

Start by factoring the left side.

We need to find two numbers that have a product of -210 (6 * -35) and a sum of 11...

-10*21=-210

-10+21=11

We can rewrite 11x as -10x+21x...

[tex]6x^2-10x+21x-35=0[/tex]

Then, factor the first and second half of the left side individually:

[tex]2x(3x-5)+7(3x-5)=0[/tex]

Since 2x and 7 are both being multiplied by 3x-5, we can combine them to get:

[tex](3x-5)(2x+7)=0[/tex]

Divide the equation by 3x-5:

2x+7=0

Subtract 7 from both sides

2x=-7

Divide both sides by 2

x=-7/2=-3.5

Now, we also have to consider another answer, in which we divide the equation by 2x+7 instead of 3x-5:

3x-5=0

Add 5 to both sides

3x=5

Divide both sides by 3

x=5/3≈1.7

y = 3 * 2^-1

y = 3 * 1/2

y = 3/1 * 1/2

y = 3(1) / 1(2)

y = 3/2

y ≈ 1 1/2
