Answer:

x=30°

Step-by-step explanation:

Angles 4x and 2x are supplementary, so 4x+2x must be equal to 180°.

Therefore, to solve this problem, we must use the equation, "4x+2x=180°.

4x+2x=180

6x=180

x=30°

Hope this helps..

The solution of the equation is,

⇒ x = - 2

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ 3 (4x + 6) = 9x + 12

Now,

Solve the equation as;

⇒ 3 (4x + 6) = 9x + 12

⇒ 12x + 18 = 9x + 12

⇒ 12x - 9x = 12 - 18

⇒ 3x = - 6

⇒ x = - 6/3

⇒ x = - 2

Answer:

10/3

Step-by-step explanation:

6 length is 2 height.

So 10(6+4) length is 10/3 height

Answer:

x = 10/3

Step-by-step explanation:

These two triangles are similar by AA similarity, as they share angle A, and both have right angles.

Not we can set up a ratio:

6/(6+4) = 2/x

6/10 = 2/x

3/5 = 2/x

Multiply both sides by 5x,

3x = 10

Divide both sides by 3:

x = 10/3

Answer:

Step-by-step explanation:

(12g²h⁷)(3g⁻²h⁻⁴) = 12 * 3 * g²⁺⁽⁻²⁾ * h⁷⁺⁽⁻⁴⁾

                            = 36 * g⁰ * h³

                            = 36 * 1 * h³

                            = 36h³

Any variable or constant to the power of zero is 1

Step-by-step explanation:

Answer:

V = 62.8 units³

Step-by-step explanation:

Once the area of a circle is:

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

The volume of a cylinder is:

[tex]V=\pi r^2 h[/tex]

where [tex]h[/tex] is the height of the cylinder.

Once, [tex]r=2 \text{ and } h=5[/tex]

[tex]V=3.14 \cdot 2^2 \cdot 5\\V=3.14 \cdot 20\\V=62.8 \text{ units cubed}[/tex]

Answer:

Step-by-step explanation:

Well, first of all the shape needs to be a rectangle not a square. And i think you do not understand how coordinates work.

The coordinate (-1, 4). The first number -1 is the number on the x-axis, 4 is the number on the y-axis. Same thing with the other coordinate.

After you put down the two dots, you know that the Perimeter is 24 cm.

P = 2(a + b) = 24 => a+b = 12 => a = 4 => b = 8

The sides are 4 and 8 units long.

Answer:

The height of trapezoid is 7km.

Step-by-step explanation:

Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b represents the length and h is the height. By substituing the values, you are able to find the height :

[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]

Let a = 4km,

Let b = 8km,

Let area = 42km²,

[tex]42 = \frac{1}{2} \times (4 + 8) \times h[/tex]

[tex]42 = \frac{1}{2} \times 12 \times h[/tex]

[tex]42 = 6 \times h[/tex]

[tex]6h = 42[/tex]

[tex]h = 7 \: km[/tex]

Answer: 5 miles

Step-by-step explanation:

Answer:

5/6x = -10

=> 5/6x = -10/1

by cross multiplication

=> 6x × - 10 = 5 × 1

=> 6x = 5 × 1 / -10

=> 6x = 1/-2

=> x = 1/-2 ×6

=> x = 1/-12

y = 3x^2 is compressed by 3.

As y = x^2 is the parent graph, you can see how big a difference 3 makes.

Hope this helps!

(Red: y = 3x^2)

(Blue: y = x^2)

The transformation for the given function is vertical compression or stretch.

The given functions are y=3x² and y=x².

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The graph for the given functions can be determined as follows

To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Horizontal Shift: None

Vertical Shift: None

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Compressed

Therefore, the transformation for the given function is vertical compression or stretch.

Answer: D

Step-by-step explanation:

A and C are linear equations therefore we can eliminate them.

We are left betwen C and D.

C.

x²=25

x=5, x=-5

For C, we can eliminate because when you solve for x, you get 2 linear equations. You may see the x² and think it's linear, but when you solve it, you get 2 linear equations.

We are left with D. Even if you graph it and it doesn't look like a parabola or quadratic, it is still a quadratic equaiton. The 1/ makes it split both ways.
