Help me find the value of x

Sergeu [11.5K]

We know that the entire angle is equal to 90 degrees (look at image below). This means that the sum of 4x-10 and x is 90 degrees, so you can make a formula:

4x - 10 + x = 90

Now you can solve for x

5x - 10 = 90

5x = 100

x = 20

Hope this helped!

Answer:3x • (2x2 - 3)

Step-by-step explanation:

Pulling out like terms

6.1 Pull out like factors :

6x3 - 9x = 3x • (2x2 - 3)

Trying to factor as a Difference of Squares:

6.2 Factoring: 2x2 - 3

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 2 is not a square !!

Ruling : Binomial can not be factored as the

difference of two perfect squares

Final result :

3x • (2x2 - 3)

The base of the prism in the diagram is rectangular, but the edges that are not parallel to the base are tilted. What is the vol

Aneli [31]

Answer:

Volume of the prism is 648 $cm^3$

Step-by-step explanation:

Given:

Base of the prism is rectangular in shape

Height of the prism = 6 cm

Base length of the prism= 12 cm

Base width of the prism= 9 cm

To Find:

Volume of the prism=?

Solution:

Volume of the prism ,

V= Base area of the prism x Height of the prism

Here in the figure base of the prism is in Rectangular form

So the base area of the prism = area of the rectangle

We know that the area of the rectangle is = length x height

Substituting the values

Area of the Rectangle = 12 x 9

Area of the Rectangle = 108

So the are of the base of the prism is 108 $cm^2$

Now

Volume of the prism,

V= 108 X 6

V= 648 $cm^3$

Describe how to determine if two polygons have the same size and shape.

QveST [7]

You can identify similar polygon by comparing their corresponding angles and sides. ( if they are the same the ratio of the lengths is the scale factor. Also check if their sides are proportional.)
