BD = 52BZ = 20BS = ?

Use ratios of similar triangles:

Answers

Answer:

3(x - 10)

Step-by-step explanation:

3x - 30 = 3(x - 10)

Hii!

__________________________________________________________

Answer:

3(x-10)

Step-by-step explanation:

Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.

The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain

x-10

Put parentheses around x-10

(x-10)

Next, put 3 outside the parentheses

3(x-10)

-6×-15=4×+35 i need help with this problem​

Answers

Isolate the variable by dividing each side by factors that don't contain the variable.

-6x-15+15=4x+35+15

-6x=4x+50
(Subtract 4 on both sides)

-10x=50
(Divide by 10 on both sides)

x=5

Answer:

x = -5

Step-by-step explanation:

-6x - 15 = 4x + 35

      + 15        + 15

-6x = 4x + 50

-4x   - 4x

-10x = 50

-10x/-10 = 50/-10

x = -5

PLEASE HELP ME OMG X

Answers

Answer:

Answer: 544

Step-by-step explanation:

The Surface Area of a Cuboid

Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:

[tex]S=2(xy+yz+xz)[/tex]

The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:

[tex]S=2(28*4 + 4*5+ 28*5)[/tex]

[tex]S= 2*272 = 544[/tex]

The surface area is [tex]544 cm^2[/tex]

−4x−8>−20

Answers

Answer:

x < 3

Step-by-step explanation:

−4x − 8 > −20

Add 8 to both sides.

-4x > -12

Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.

-4x/(-4) < -12/(-4)

x < 3

Answers

The required x-intercept is (7, 0) and the y-intercept is (0, 3).

What is the intercept in the equation?

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
To find the x-intercept, we need to find the point at which the graph intersects the x-axis. This occurs when the y-coordinate is zero.

The x-intercept is therefore (7, 0).

To find the y-intercept, we need to find the point at which the graph intersects the y-axis. This occurs when the x-coordinate is zero.

The x-intercept is therefore (0, 3).

Thus, the x-intercept is (7, 0) and the y-intercept is (0, 3).
