A^2-5a = 6
a^2-5a-6 = 0
Discriminant = (-5)^2-4(1)(-6) = 49
Discriminant is positive so there are two solutions
The geometric sequence is B: 32
Answer:
603 miles in 3 days
Step-by-step explanation:
Let's find out how many miles in 1 day:
- 1,005 ÷ 5 = 201
- So, Sarah drives 201 miles in 1 day
Let's find out how many miles in 3 days:
- 3 days = 1 day × 3
- 3 days = 201 × 3
- 3 days = 603 miles
I hope this helps!
