Find the value of x. (2x +4)° 2x-9)°​

Answer:

6h+14k

Step-by-step explanation:

Multiply 2by 3h which gives 6h then multiply 7k by 2 which gives 14k.

Since 6h and 14k are not like terms u cannot add so your answer will be 6h + 14k.

Answer:

9h² + 42hk + 49k²

Step-by-step explanation:

Given

(3h + 7k)²

= (3h + 7k)(3h + 7k)

Each term in the second factor is multiplied by each term in the first factor, that is

3h(3h + 7k) + 7k(3h + 7k) ← distribute both parenthesis

= 9h² + 21hk + 21hk + 49k² ← collect like terms

= 9h² + 42hk + 49k²

Write the equation of line in slope-intercept form. Line parallel to y = 0.5x + 3 that passes through the point (−9,12)

Answer:

y - 12 = 0.5(x + 9)

Step-by-step explanation:

We want to find the line parallel to y = 0.5x + 3 that passes through the point (−9,12).

To some this, we will use the equation;

y - y1 = m(x - x1)

Here, x1 = -9, y1 = 12, m = 0.5

Thus;

y - 12 = 0.5(x - (-9))

y - 12 = 0.5(x + 9)

Answer:

There should be 5 lines of symmetry.

Step-by-step explanation:

Carla's draw only one line of symmetry but in a regular pentagon there should be 5 line of symmetry.

Here,

Carla was asked to draw all the lines of symmetry for a regular pentagon.

She drew the picture as shown.

We have to find Carla's mistake.

What is Regular Pentagon?

A regular pentagon is a pentagon that has 5 equal sides and 5 equal angles.

Now,

As shown in figure,

Carla's draw only one line of symmetry.

But in a regular pentagon there should be 5 line of symmetry.

Hence, There should be 5 line of symmetry.

Option 4 is true.

Answer:

(B)45°, 67.5°

Step-by-step explanation:

A regular polygon is a polygon in which all the sides are equal.

An Octagon is a polygon with 8 sides.

Since it is a Regular polygon, the following holds:

1.The Radii are equal

2. The angle Subtended by two radii are equal for all triangles in the octagon.

3. There are 8 Isosceles triangles in the octagon.

(a)Measures of angle formed by Two radii

From the centre of the octagon, there are 8 equal angles.

Sum of Angle at a point= 360°

Each Angle=360°÷ 8 = 45°

The measures of angle formed by two radii is 45°.

(b)a radius and a side of the polygon.

Since the triangles are Isosceles, the base angles at the side of the octagon are equal.

Let x be the angle made by a radius with a side.

From (a) above,

x+x+45°=180°(Sum of Angle in a Triangle)

2x=180-45°

2x=135°

x=135°÷2=67.5°

The angle between a radius and a side of the polygon is 67.5°.

Answer:

64

Step-by-step explanation:

- 12 + 16 - 5 (-12)
- 12 + 16 + 60
4 + 60
= 64

Answer:

64

Step-by-step explanation:

If x = –12 and y = 16, evaluate x + y – 5x.

Solution,

= x + y - 5x

= -12 + 16 - 5 ( -12 )

= - 12 + 16 + 60

= - 12 + 76

= 64

Answer:

Chicago

Step-by-step explanation:

Compare the temperatures:

-4, -14, -11, -13

Numbers become smaller to the left on the number scale.
For instance, -10 is less than -5.

So, -13, -11, and -4 are all greater than -14.

And the lower the temperature, the colder it is.

Thus, Chicago is the coldest.

Answer:

in explanation

Step-by-step explanation:

Input to output so for the input when it is 1=6 because it starts at 5 and then 8 what I mean is when the input comes out the output is going to be 3 more greater than last time.

So 1=6 so 6 is 5 more then

2 to 10=8 so 5 more went to 8 more.

Next is 3 and 14 so 3 more again because 8 + 3=11 so in that case that next number is 4 it will be 14 more

So 14 more than 4=18 and that is the output.

Also for the output it adds 4 for the numbers 6 + 4=10 + 4=14+ another 4=18.

And input is just plus 1.

Hope it helps have a great day:)

Answer:

Step-by-step explanation:

We can first find the GCD or GCF of 28 and 91. 91 in its simplest form is 13*7. 28 in its simplest form is 2*2*7. The only common factor they have is 7, so 7 is the GCD. We can divide both by 7 to get [tex]\frac{4}{13}[/tex]

Answer:

Hey there!

In order to simplify the first expression, we need to use the Distributive Property:

4(7x-4)=28x-16 (the same as 4*7x-4*4)

Hence, the equivalent expressions are

[tex]\boxed{\boxed{\bold{28x-16\;and\;4*7x-4*4}}}[/tex]

[tex]\rule{200}{2}[/tex]

In order to simplify the second expression, we need to combine like terms:

11y+3y+9y

11y+12y ✓

23y ✓

Hence, the equivalent expressions are

[tex]\boxed{\boxed{\bold{11y+12y\;and\;23y}}}[/tex]

Hello! The answer is 69.11

Step-by-step explanation:

This is the formula you use: Circumference = 2 * π * r

r = Radius, the radius is just half of the (22) diameter, so half of 22 is 11.

2 * π * 11 =  69.11

Answer:

1.75 + 0.3x = 7.45; 19 minutes

Step-by-step explanation:

The cost of the phone call is found by 1.75 + 0.30 multiplied by the number of minutes the calls lasts.  The cost of the call is 7.45 so 1.75 + 0.3x = 7.45.  Begin by subtracting 1.75 from each side of the equation.  That leaves 0.3x = 5.7.  Then divide both sides by 0.3.  This gives x = 19.

Answer:

r ≈ 12.1

Step-by-step explanation:

from the diagram the radius r of the circle is GM and GE and

GA = r - 4

using Pythagoras' identity in right triangle AGM , then

9² + (r - 4)² = r² ← expand factor on left using FOIL

81 + r² - 8r + 16 = r² ( subtract r² from both sides )

97 - 8r = 0 ( subtract 97 from both sides )

- 8r = - 97 ( divide both sides by - 8 )

r = [tex]\frac{-97}{-8}[/tex] ≈ 12.1 ( to 1 dec. place )

Step-by-step explanation:

Answer:

(0,6)

Step-by-step explanation:

First, deal with the reflection. Reflecting the triangle over the x axis will reflect it vertically into the upper right quadrant. Because it is reflected vertically, the x values of the vertices will not change and the y values will be the negative of whatever value they are originally. If the coordinates of each vertex are (x,y), you can easily find their new location by changing it to (x,-y). After the reflection, the coordinates of the vertices are as follows:

A = (2,6) [originally (2,-6)]

B = (2,1) [originally (2,-1)]

C = (5,6) [originally (5,-6)]

Now, deal with the translation. A translation of -5 units horizontally means that the triangle will be moving 5 units to the left. The y values will be unaffected by the translation. To find the new coordinates, subtract 5 from the x values of the coordinates after the reflection.

A = (-3,6)

B = (-3,1)

C = (0,6)

Therefore, the answer is (0,6).

Answer:

B - In each round, the number of emails is 3 times the round before.

Step-by-step explanation:

This is because each time down, it is being multiplied by 3 again.

3

3 times 3 = 9

3 times 9 = 27 (can also be 3 times 3 times 3)

3. 3x = 12

An open statement in math means that it utilizes variables, and can only be concluded as being "true" or "false". The problem would result in asking whether or not it is always true or not. In this case, x will be true when you plug in 4, however, it will not be true when you plug in any other number. Therefore, it is a closed statement that can be falsified.

4. Open.

The statement can be true if the variable g is 35, however, it is false if it is not. An open statement concludes that it may or may not be correct, thereby being open.
