Answer:
Step-by-step explanation:
Rashad has 25 stamps.
He shared them equally among himself and four friends.
Total number of member to get stamps = 4 + 1
= 5
Shared equally to 5 member.
Each one get = 25÷5
Rashad found two more in pocket.
Rashad has total stamps = 5 + 2
= 7
Expression which shows number of stamps Rashad has or 7
-16t^2+400=0
16t^2=400
take square root on both sides.
4t=20
t=20/4
t=5
