Plz for brainliest did micah add the expressions correctly? explain your answer using complete sentences.

Micah's end result is incorrect.

He added the rational expressions correctly, but then incorrectly "simplified" the sum. The sum (x²+x-4)/(x²+3x+2) cannot be simplified further.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
