Answer:
A and C
Step-by-step explanation:
6.8 - 2.17 = 4.63
7.23 - 2.17 = 5.06
This is the quadratic formula.
3.14159265359
So the 7th number would be 2.
Answer: 8 1/2 is less than 9 1/2, 8 1/2< 9 1/2
1. x
2. x + 2
3. x + 4
x + 4 + 2x = 25. Second option is the answer.
Combine like terms
3x + 4 = 25
Subtract 4 from both sides
3x = 21
Divide both sides by 3
x = 7
