Please show your work so I can understand what you're doing.

Answer 1

Well here are my steps to answer this:

a^2 + 5a + 4 / a^3

a^2 - a^2 + 5a +4 / a^3 - a^2

5a + 4 / a ^1

So...

Unless I have a value for a I have to substitute it as 1.

5 + 4 / 1

9 / 1 = 9

Your answer is 9!

Answer 2

a^2+5a+4 / a^3 divided by a^2+3a+2 / a^2-2a

Answer 3

a^2 + 3a + 2 / a^2 - 2a

a^2 - a^2 + 3a + 2 / a^2 - 2a - a^2

3a + 2 / 2a

2a - 3a + 2 / 2a - 2a

1a + 2

So...

Unless I have a value for a I have to substitute it as 1.

1 + 2 = 3

So...

We have to plug in are numbers and end up with 9 divided by 3 which equals 3.

Your answer is 3!
