Answer is A

Step-by-step explanation:

a+a+a+a+b+b =4a+2b

The set builder notation of the inequality  - 3(7n + 3) < 6n is,

{n : n ∈ R, n > - 3 }.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, An inequality - 3(7n + 3) < 6n.

Now, distributing the terms we get,

- 21n - 9 < 6n.

- 21n - 6n < 9.

- 27n < 9.

27n > - 9.          (Think of moving the variable to the other side to make it

                                                                                                        positive).

n > - 27/9.

n > - 3.

Given:

The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."

To find:

Whether the given statement in true or false.

Solution:

Area of circle is

[tex]A=\pi r^2[/tex]

Where, r is the radius of the circle.

Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is

[tex]A_1=\pi (r_1)^2[/tex]

The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:

[tex]r_2=1.5r_1[/tex]

The area of the new circle is

[tex]A_2=\pi (r_2)^2[/tex]

[tex]A_2=\pi (1.5r_1)^2[/tex]

[tex]A_2=2.25\pi (r_1)^2[/tex]

[tex]A_2=2.25A_1[/tex]

The area of the new circle is 2.25 times the area of the original circle.

Therefore, the given statement is false.

[tex]x^{3} -x^{2} -5x-3[/tex]

Step-by-step explanation:

you use distributive property for this, or you can do the box method

distributive:

[tex]x(x^{2} +2x+1)-3(x^{2} +2x+1)[/tex] (you multiply the second equation by x-3)

then distribute, or multiply everything

[tex]x^{3} +2x^{2} +x-3x^{2} -6x-3[/tex]

Answer:

45/8 or 5 5/8

Step-by-step explanation:

2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8.  you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.

Answer:

45/8 or 5 5/8

Step-by-step explanation:

When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.

Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.

                                      Numerators: 9 x 5 = 45

                                      Denominators: 4 x 2 = 8

So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

Answer:

B = 12.8 cm (to 1.d.p)

D = 24.1 cm (to 1.d.p)

Step-by-step explanation:

Using Pythagoras Theorem:

B: 4^2 + 3.5^2 = 28.25

square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle B = 12.8 cm (to 1 decimal place)

D: 10^2 - 6.5^2 = 57.75

square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle D = 24.1 cm (to 1 decimal place)

Step-by-step explanation:

Answer:

40 feet tall

Step-by-step explanation:

6/2 =3

?/2 =20

*2    *2

? = 40

you do inverse operations because 6 divided by 2 is 3... the ? is the variable for how tall the building is... ? divided by 2 = 20 so you multiply 2 and 20 to get the total height

Answer:

X= - 2

Step-by-step explanation:

-3 (5x+6) - 3x = 6-6x

Remove the parentheses

-15x-18-3x=6-6x

Collect the like terms

-18x-18=6-6x

Move the variable to the left-hand side and change its sign

18x+6x=6+18

Collect the like terms

-12x=24

Divide both sides

X=-2

Answer:

the slope is POSITIVE (answer A)

Step-by-step explanation:

The line goes through: (-1, -2)  and ( 2, 1)

Then the slope can be calculated as:

slope = (y2 - y1) / (x2 - x1)

in our case:

slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1

Therefore, the slope is POSITIVE (answer A)
