This is how you can attain your goals. in this article, are one of the answer and question example that you might possibly implement to practice and further enhance your understanding and also give you insights that might assist you to preserve your study in school.

## Question:

If DF = 9x-39, find EF.

## Answer:

The** measure** of** EF is 58**

From the line given, **DF** is **equal** to the **sum of DE and EF**

DF = DE + EF

Given the following

DE = 47

EF = 3x+10

DF = 9x-39

**Substitute** the **given** values into the **formula**

47+3x+10 = 9x-39

57+3x = 9x-39

3x-9x = -39-57

-6x = -96

x = -96/-6

x = 16

Get EF

Since EF = 3x+10

EF = 3(16)+10

EF = 48+10

EF = 58

Hence** **the** value of EF is 58**

From the answer and question examples above, hopefully, they can potentially assist the student answer the question they had been looking for and notice of every detail declared in the answer above. You can potentially then have a discussion with your classmate and continue the school learning by studying the subject alongside one another.
