Answer:

A= [tex]4x+8[/tex]

B= [tex]8x+6x \\or\\ 16x[/tex]

C= [tex]8x+12[/tex]

D= [tex]6x+6y+6z[/tex]

Step-by-step explanation:

Distributing, or the means to divide something/create a share or part of something is when we multiply the sum of two or more addends by a number to achieve the same result as multiplying each addend individually by the number then adding the products together.

With this said, part A would look like this:

[tex]4(x+2)\\4(x) + 4(2) = ?\\4x + 8[/tex]

Now, the problem doesn't specifically state to solve the problem, but if you wanted too it would look like this:

[tex]4x + 8=0\\-8 \\4x=-8\\divide 4\\4=GCF\\x=-2[/tex]

Since we are just looking for the equation, the following problems would appear as so:

B:

[tex](6+8)*x\\x(8) + x(6)\\8x+6x\\14x[/tex]

C:

[tex]4(2x+3)\\4(2x)+4(3)\\8x+12[/tex]

D:

[tex]6(x+y+z)\\6(x) +6(y)+6(z)\\6x+6y+6z[/tex]

Another way to view the distributive property is that your distributing the number outside the parenthesis to all the number inside as such.

I would be happy to help you again in the future and hope that this provided you with some clarification! Have a nice day! :D

it would be 6*7=42 plus (13-7)*(6-3)/2 which equals 9, so 42+9=51

Answer:

Step-by-step explanation:

The better buy is the one where you get more area of pizza per dollar (area/price).

Since the problem gives diameter, we assume the pizzas are circle-shaped.

Circle Area = pi x (radius)², and radius r = 1/2 of diameter d.

*************************************************************************************

Pizza 1: d = 8 and price is $10

r = 1/2 x d = 4

Area of Pizza 1 = πr² = π(4)² = 16π

*** area/price for Pizza 1 = 16π/$10 = 1.6π area per dollar

**********************************************************************************

Pizza 2: d = 14 and price is $16

r = 1/2 x d = 7

Area of Pizza 2 = πr² = π(7)² = 49π

*** area/price for Pizza 2 = 49π/16 = 3.0625π area per dollar

***********************************************************************************

Pizza 2 is the better buy, with more pizza per dollar.

Step-by-step explanation:

Answer:

Statement is - 3x + 8 = 14, x = 2

Let P - 3x + 8 = 14 , Q - x = 2

Conditional statement is -If 3x + 8 = 14 , then x = 2.

Inverse Statement is - If 3x + 8 ≠ 14 , then x ≠ 2.

Converse statement - If x = 2 , then 3x + 8 = 14

Contra-positive statement - If x ≠ 2 , then 3x + 8 ≠ 14

Answer:10

Step-by-step explanation:

Answer:

n=-18

Step-by-step explanation:

subtract 8 from both sides.

then you do -10 subtracted by 8 and thats -18.

Answer:

there's no angle z theres only x but the answer for x is 133

Step-by-step explanation:

Answer:

y = -3 - x/2

Step-by-step explanation:

x + 2y = -6  

You have to isolate y by minusing x on both sides

2y = -6 - x    

Then you will isolate y by dividing both sides by 2

y = -3 - x/2

Answer:

0.4 and 0.2.

Step-by-step explanation:

For the first problem, you divide 5 by 2.

[tex]\frac{2}{5} = 0.4.[/tex]

This gives you 0.4

For the second problem, we simplify the fraction, first.

[tex]\frac{5}{25} = \frac{1}{5} .[/tex]

Then, we divide 1 by 5.

[tex]\frac{1}{5} = 0.2.[/tex]

This gives you 0.2.

Answer:4124966.126

Step-by-step explanation:

Distance between star from the sun is d = 4124966.128 AU

What is Trigonometry?

Trigonometry is the branch of mathematics that deals with particular angles functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle.

The astronomical unit distance between the star and the Sun can be calculated using the trigonometric function.

As per the given data:

distance from Earth to the Sun (P) = 1 AU

θ = 0.00001389 degrees

From tanθ:

tanθ = P/B

{P = perpendicular and B = base}

From the diagram:

tanθ = 1/d

tan(0.00001389) = 1/d

d = 1/tan(0.00001389)

d = 4124966.128 AU

The separation between the sun and the star is d = 4124966.128 AU.

Answer: Rachel recieved 45 votes.

Step-by-step explanation: Any easy way to solve this is to has the demonimator equal the total amount of votes. So in the questions, 8 is the denominator and 72 is the total amount of votes. To get from 8 to 72, you need to multiple 8 by 9. And whatever you do to the denominator, you must do to the numerator. So, 5 times 9 equal 45 which is the number of votes Rachel recieved.

Answer:

cos 0=90 degrees

Step-by-step explanation:

If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.

[tex] \sin(90) = \cos(0) [/tex]

and since sin 90 equal 1 cos of 0 equal 1.

What if we switch angles

Well they are still equal

[tex] \sin(0) = \cos(90) [/tex]

But this time sin of 0 is 0 and cos 90 is 0.

If the function sin 90° is 1, then the cos90° value is zero.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that sin 90° is 1

We need to find the cos 90°.

We know that the function sine is Opposite side/ hypotenuse

cosine is Adjacent side/ hypotenuse.

sine is reciprocal of cosec

Sine = 1/ cosec

cosine = 1/ sec

The value of cos90 is zero.

Hence, If the sin 90° is 1, then the cos90° value is zero.
