8 The perimeter P of a regular pentagon is 90 cm. What is the length x of each
side?

Answer: AB = 6

Step-by-step explanation:

If CD = 12 , AC also = 12

B is the midpoint of AC so one side = 6

AB is one side of AC , so AB = 6

I am not a professional, I am simply using prior knowledge!

Note- It would mean the world to me if you would mark me brainliest!

The Distance between AB will be 12 units

The steps are as follow:

AC = 2 x CD = 2 x 12 = 24 units

AB = AC/2

AB = 24/2 = 12 units

So Distance between points AB will be 12 units

Answer:

Step-by-step explanation:

Answer:

h = (3 - x)/2

Your answer is not correct.

Step-by-step explanation:

⅓(x + 2h) + 1 = 2

Subtract 1 from both sides;

⅓(x + 2h) + 1 - 1 = 2 - 1

This gives;

⅓(x + 2h) = 1

Multiply both sides by 3;

⅓(x + 2h) × 3 = 1 × 3

This gives;

x + 2h = 3

Subtract x from both sides to get;

2h = 3 - x

Divide both sides by 2 to get;

h = (3 - x)/2

−5 <n≤2 - 5 <n≤2

Answer:

- 4, - 3, - 2, - 1, 0, 1, 2

Step-by-step explanation:

Given

- 15 < 3n ≤ 6 ( divide the 3 intervals by 3

- 5 < n ≤ 2

Thus n can have values from - 4 to 2, that is

- 4, - 3, - 2, - 1, 0, 1, 2

Answer:

Step-by-step explanation:

Simplifying

3(2x + -1) = 21

Reorder the terms:

3(-1 + 2x) = 21

(-1 * 3 + 2x * 3) = 21

(-3 + 6x) = 21

Solving

-3 + 6x = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 6x = 21 + 3

Combine like terms: -3 + 3 = 0

0 + 6x = 21 + 3

6x = 21 + 3

Combine like terms: 21 + 3 = 24

6x = 24

Divide each side by '6'.

x = 4

Simplifying

x = 4

Answer:

2/3x + 7s

[tex]2\frac{7}{24x} + 5\frac{5}{6}[/tex]

Step-by-step explanation:

[tex]2 \frac{1}{8x}+ \frac{3}{4x} + \frac{1}{6} - \frac{7}{12x} + 5\frac{2}{3}[/tex]

find a common denominator for the x values: GCD = 24

so multiply each fraction with an x to get the common denominator

[tex]2 [(\frac{3}{3} )(\frac{1}{8x})] + [(\frac{6}{6})(\frac{3}{4x})] + \frac{1}{6} - [(\frac{2}{2})(\frac{7}{12x})] + 5\frac{2}{3}[/tex]

then multiply it out

[tex]2\frac{3}{24x} + \frac{18}{24x} + \frac{1}{6} - \frac{14}{24x} + 5\frac{2}{3}[/tex]

then, find the GCD for the fractions without x: GCD = 3

[tex]2\frac{3}{24x} + \frac{18}{24x} + \frac{1}{6} - \frac{14}{24x} + 5[(\frac{2}{2})( \frac{2}{3})][/tex]

then multiply it out

[tex]2\frac{3}{24x} + \frac{18}{24x} + \frac{1}{6} - \frac{14}{24x} + 5\frac{4}{6}[/tex]

finally, combine like terms:

Answer:

Identifying and moving the base is the key to changing from logarithmic form into exponential form. Identifying the base of the logarithmic equation and moving the base to the other side of the equal sign is how to change a logarithmic equation into and exponential equation.

Example- log 8 base 2=3

then 2^3=8

The opposite of a logarithmic function is an exponential equation, and vice versa

As a general rule, we have the following equation to convert a log function to an exponential.

[tex]\log_ba = x \to a = b^x[/tex]

Take for instance, we have the following logarithmic function

[tex]\log_216 = x[/tex]

The equivalent exponential equation is:

[tex]16 = 2^x[/tex]

Answer:

4 a + 2b = 360 ----->equation 1

a + b = 116 --------> equation 2

a = 64 °

b = 52°

Step-by-step explanation:

The sum of all of the internal angles would be 360°.  Since we have four "a"s and two "b"s, we have:

4a + 2b = 360

Then told that the largest internal angle of the parallelogram is 116 degrees, so:

a + b = 116

We now have a system of two equations and two unknowns.

I'll simplify the first equation by dividing both sides by 2, then multiplying the second equation by -1 to prepare for solving by elimination:

2a + b = 180

-a - b = -116

----------------------  Add the equations together to get:

a = 64°

Now we can solve for b:

a + b = 116

64 + b = 116

b = 52°

So the values of "a" and "b" are:

a = 64° and b = 52°

Answer: 37.5 minutes

Step-by-step explanation:

It takes Jahanna 50 minutes to deliver to 40 customers.

On Sunday however, she has to deliver to only 30 customers.

Assume that the amount of time it will take her is x minutes and use direct proportion:

50 minutes          :       40 customers

x minutes             :       30 customers

Cross multiply:

40x = 50 * 30

40x = 1,500

x = 1,500/40

x = 37.5 minutes

[tex]Perimeter = 4x+16[/tex]

Step-by-step explanation:

Given

[tex]Rug=x[/tex]

Determine the perimeter of the room

The room is 3ft wider.

So:

[tex]Width = Rug + 3[/tex]

[tex]Width = x + 3[/tex]

The room is 5ft longer,

So:

[tex]Length = Rug + 5[/tex]

[tex]Length = x + 5[/tex]

The perimeter is:

[tex]Perimeter = 2 * (Length + Width)[/tex]

[tex]Perimeter = 2 * (x+5+x+3)[/tex]
