Uhh 27 not really sure tbh
Answer:
14r−t+8w
Step-by-step explanation:
Let's simplify step-by-step.
8w+5r−t+9r
=8w+5r+−t+9r
Combine Like Terms:
=8w+5r+−t+9r
=(5r+9r)+(−t)+(8w)
=14r+−t+8w
Answer:
=14r−t+8w
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
The answer is d because 4+8=12 and they are 4 units away from eachother:)
40/24+9/24= 40+9/24 = 49/24
