In pretty sure the answer is b
D = 20 , v = 19
20v + 12d - 6v
= 20 (19) + 12 (20) - 6 (19)
= 380 + 240 - 114
= 620 - 114
= 506
When d = 20 and v = 19
20v + 12d - 6v = 506
Answer:
20.4 ft
Step-by-step explanation:
Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.
6/9.7 = ?/33
A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.
This gives you 20.4 ft
