Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:
<em>multiply both sides by 8</em>

Answer:
see explanation
Step-by-step explanation:
Note the common ratio r between consecutive terms of the sequence
r = 6 ÷ 3 = 12 ÷ 6 = 24 ÷ 12 = 48 ÷ 24 = 2
The explicit rule for a geometric sequence is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 3 and r = 2, thus
= 3
← explicit rule
Answer:
d
Step-by-step explanation:
using the distance formula
d =
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (10, 1 )
d =
