Answer:
-x - 3
Step-by-step explanation:
x-(2x + 3)
=> x-1(2x + 3)
=> x - 2x - 3
=> -x - 3
Therefore, this is the solution. Hoped this helped.

CPCTC and Parallel concurrency theorem
Answer:
9cm
Step-by-step explanation:
The formula for the area of a parallelogram is base x height.
You have the height, 7cm, and the area, 63cm^{2}[/tex].
So the equation is B x 7 = 63. Simply take 63 divided by 7 and you get 9.
Answer: 9cm
John has borrowed $6.50 from his friends and $11.75 from his sister. To find how much money he needs to repay you can just add up the amount of money he has borrowed.
Make an equation to solve for this, where x = amount of money John needs to repay. Make the amount of money John borrowed add up to x. Your equation should look like:
$6.50 + $11.75 = x
Combine like terms (add 6.50 and 11.75).
$18.25 = x
After solving the equation, you have figured out that John need to repay $18.25 in total.

Step-by-step explanation:
Alright, lets get started.
Before moving to the answer, we must be familiar with the concept of similar triangles.
Please refer the diagram I have attached.
Two triangles are called similar if their corresponding angles are congruent and the corresponding sides are in proportion.
As we can see in diagram I have attached, both triangles have corresponding angles congruent, means



Hence both triangles are similar.
Now coming back to our question, as we can see, there is no angle is congruent in both triangles, so these are not similar triangles.
Hence, they are not similar because their corresponding angles are not congruent. : Answer
