Answer 4

i actually don't know

Answer 5

then let's break it down :)
what is

--- x ---- = ?
5t 1

Answer 6

60t
---
5t

Answer 7

which can be simplified :)
because like how 2 over 2 = 1
t over t also equals 1
then simplify the 60 over 5

Answer 8

12

Answer 9

yep!
now let's do
3 30t
-- x ---- = ?
3t 1

Answer 10

90t
--- = 30
3t

Answer 11

yep :D
so for the numerator you now have 12 - 30 =

Answer 12

-18

Answer 13

ok :)
now let's do the denominator:
1 30t
-- x ---- = ?
2t 1

Answer 14

30t
--- = 15 but times two since it is plus the same fraction so 30.
2t

Answer 15

Answer 18

thanks.

Answer 19

hey do you think you have time to help me with another problem.

Answer 20

sure :)

Answer 21

ok

Answer 22

Simplify the difference.

Answer 23

do you know how to factor
b² - 2b - 8 = ?

Answer 24

(b+4)(b-2)

Answer 25

mmm close :) check the signs

Answer 26

(b-4)(b+2)

Answer 27

yep :)
now factor
b² + b - 2 = ?

Answer 28

(b+2)(b-1)

Answer 29

yep! :)
so now you have
(b-4)(b+2)
----------
(b+2)(b-1)

then the (b+2) s cancel out because like how 2 over 2 = 1
then what would you be left with? :)

Answer 30

(b-4)
-----
(b-1)

Answer 31

yep! :) and that would be your answer :)
