Step-by-step explanation:
If the triangles are similar, then the corresponding sides are in proportion:
![\dfrac{20}{20+8}=\dfrac{3x}{4x+2}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B20%2B8%7D%3D%5Cdfrac%7B3x%7D%7B4x%2B2%7D)
![\dfrac{20}{28}=\dfrac{3x}{4x+2}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B28%7D%3D%5Cdfrac%7B3x%7D%7B4x%2B2%7D)
![\dfrac{20:4}{28:4}=\dfrac{3x}{4x+2}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%3A4%7D%7B28%3A4%7D%3D%5Cdfrac%7B3x%7D%7B4x%2B2%7D)
<em>cross multiply</em>

Answer:
3
Step-by-step explanation:
I'm not sure how to explain without pictures, I apologize.
38.94 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down
38.94
The number is 4, so we round down. 38.94 becomes 38.9
65.45 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down.
65.43
The number is 3, so we round down. 65.43 becomes 65.4
38.9+65.4= 104.3
If you were to estimate 38.94+65.43, we round the number to numbers that we can easily calculate in our head. 38.94+65.43 becomes 40+65
40+65=105
