Start with the sum of x and 9, giving the expression

This is divided by 2 so

This equals 3x so the equation is

This can the be solved.
Multiply both sides by 2 to get

Then take x from both sides

Divide by 5 to get the value for x
Answer:
4^2+2^2, 5^2, 6^2-6
Step-by-step explanation:
4 to the power of 2 is 16 and 2 to the power of 2 is 4. 16+4 is 20.
5 to the power of 2 is 25 which is greater than 20.
6 to the power of 2 is 36 minus 6 is 30 which is greater than 25 and 20.
The way to solve is using order of operation PEMDAS. Its very easy. You should be able to solve it yourself. I'll give you the first 3 answers:
1. g/6=x
2. x=1/2u+1
3. z-m=x
I would give you all the answers but it would be best if you did it yourself. You teacher and parents would be much happier if you learnt the skill. Hope this answer helps! Mark as brainliest! :)
<span>d. Two triangles are similar if they have two corresponding angles congruent.
this is the best described option

Given:



To find:
The value of a and PQ.
Solution:
We have,

(CPCTC)
So,


Isolating variable terms, we get


Divide both sides by -2.


Now,




Therefore, the value of a is 8 and the value of PQ is 28.
