Answer:
=2x²-8x-24 is the answer
Step-by-step explanation:
=(2x+4)(x-6)
opening brackets by multiplying
=2x(x-6)+4(x-6)
=2x²-12x+4x-24
adding like terms
=2x²-8x-24
i hope this will help you :)

Step-by-step explanation:
Jaymie will measure the segment and then place the point just across from the line's beginning point to create a congruent segment that shows the similarity between them.
<h3>What are the conditions of the congruent triangle?</h3>
Triangles that are equivalent in terms of size and form are known as a congruent triangle.
Segments will be built using the straightedge, and measurements will be taken using the compass. They will pick a starting point and draw a line using the straightedge, then use the compass to finish the job.
To make the congruent segment, Jaymie will measure the segment and then position the point that is opposite from the line's starting point.
Jaymie, on the other hand, will have to work a bit harder with the compass since she will need to draw a semi-circle in the original angle and transfer this measurement to the new line in order to create congruent angles.

Step-by-step explanation:
do that with pithagoras:
20² + 4,5² = x²
400 + 20,25 = x²
420,25 = x²
x = 
x ~ 20,5

Answer:
The numbers are 9, 19 and 76.
Step-by-step explanation:
Let's take the second number and make it a variable, like x. Now let's find all the other numbers in terms of x.
The first number in terms of x:

The second number in terms of x:

If we add them all up, these 3 numbers in terms of x must be equal to 104, so:

Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:


The first number is 9, second number 19 and the third number 76.
