Simplify. 2/3a times 2/a^2
• 4 / 3a^2; where a =/ 0
• 1 / a^2; where a =/ 0
• 4 / 3a^3; where a =/ 0**
• 4 / 3a^2

14.
Divide. x^2 + 2x + 1 over x -2 over x^2 – 1 over x^2 – 4
• (x + 1)(x + 2) over x - 1
• (x - 1)(x - 2) over x + 1***
•
• (x - 1)(x + 2) over x + 1
•
• (x + 1)(x - 2) over x - 1
•
16.
Add or subtract. 7 / x -3 + 3/ x -5
• -10x – 44 over (x - 3)(x - 5)***
• 10x – 44 over (x - 3)(x - 5)
• 10x over (x - 3)(x - 5)
• 10x + 44 ov

Answer 1

Sorry 16 is missing so choices... its • 10x + 44 over (x - 3)(x - 5)

Answer 2

9) Correct
14) Not sure what problem is --> See attachment
16) I got (10x – 44) over [(x - 3)(x - 5)]

Answer 3

Thank you and Yes that exactly right for number 14 @Directrix

Answer 4

For # 14, I got [(x + 1)(x + 2)] over (x - 1)
Check your work and then I'll check mine again, too.

Answer 5

Okay hold on (:

Answer 6

Yeah I got (x - 1)(x + 2) over x + 1 but let me check again

Answer 7

Okay I see what I did wrong

Answer 8

What did you do wrong?

Answer 9

I keep messing up the number order its confusing me a little
