<h3>
<u>The value of the number is equal to 11.</u></h3>
2x - 9 = 13
<em><u>Add 9 to both sides.</u></em>
2x = 22
<em><u>Divide both sides by 2.</u></em>
x = 11
Answer:
Step-by-step explanation:

Given:
In triangle DEF, HG is parallel to DF.
To find:
The value of x.
Solution:
In triangles DEF and GEH,
(Common angle)
(Corresponding angle)
(By AA property of similarity)
We know that corresponding sides of similar triangle are proportional.





Isolating variable terms, we get



Therefore, the value of x is equal to 4.
You're answer would be 3843000 because the number in the hundredths place is 5 so you would round up your answer
