Answer 4

lisa what is this ?

Answer 5

idk..

Answer 6

i think the answer is 1

Answer 7

after you factorized these fractions and simplify i think that you are right with 1

Answer 8

ok ?

Answer 9

lisa is it ok ?

Answer 10

yes :)

Answer 11

\[\frac{n^2+3n+2}{2}\div\frac{(n+1)}{2(n+2)}= \frac{n^2+3n+2}{2} \cdot \frac{2(n+2)}{(n+1)}\]
notice that you flip the second fraction to get rid of the division.
after factoring the top of the first fraction you get
\[\frac{\cancel{(n+1)}(n+2)}{\cancel{2}}\cdot\frac{\cancel{2}(n+2)}{\cancel{(n+1)}}=(n+2)^2\]

Answer 12

(n+2) squared is right sure
