Looks confusing in the way you put it.
Answer:
The smaller number is 22
The larger number is 30
Step-by-step explanation:
L + S = 52
L = S + 8
Set both equations equal to L.
S + 8 = -S + 52
+S +S
2S + 8 = 52
- 8 - 8
2S = 44
S = 22
To find the larger number, plug 22 in as S into the equations.
L = 30
umm I don't know hehe oops
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
