Statement 3: tri egc = tri egb
statement 4: tri ebc is equilateral.
reason 5: equilateral triangles have equal angles
A
this is a geometric sequence since there exists a common ratio r between the terms
r =
=
=
= 3
B
to obtain the next term in the sequence multiply the previous term by 3
= 3
← recursive rule
C
the n th term of a geometric sequence is
=

where
is the first term in the sequence
= 7 ×
← explicit rule
Answer: 20% increase
Step-by-step explanation:
30-25=5 solve for x (5*100)/25 = 20
Hey there! You have to use PEMDAS.
Doing so will get you the answer choice of B
