Let x = length of segment EF.
Assume that
(a) line segments AD, EF, and BC are parallel, and
(b) the vertical distance between AD and EF is equal to the vertical distance between EF and BC.
Then from similarity between geometric shapes, we can write


x=3.2 (nearest tenth)
Answer: B.
3.2
Here you go I hope this helps.
Answer:
-$173
Step-by-step explanation:

The factor is x-6 since the two factors of your equation are (6x-6) and (x-6)
It seems that you are looking for the yield of the shares of stocks after they were sold.
To solve,
yield =( current total amount- previous total amount) / previous amountwherecurrent amount = $9.9/share*700share+ $18previous=$9.29/share*700 share
yield=[ (9.9*700)+18] -(9.29*700)/(9.29*700) x 100
yield= 6.8%
Shares of stocks yield = 6.8%
