A and C are the same. They also make the most sense for an answer.
Answer:
6 3/4
Step-by-step explanation:
y = abˣ
16 = ab¹
9 = ab⁵
ab⁵ / ab¹ = 9 / 16
b⁴ = 9/16
b² = 3/4
7th term: y = ab⁷ = ab⁵ x b² = 9 x 3/4 = 27/4 = 6 3/4
First take out the GCF
-3x(x^2-5x-14)
-3x(x-7)(x+2)
-7+2=-5
-7*2=-14
Answer: D
