5 • 3n
A. 15, 30, 45, 60
B. 5, 15, 45, 135
C. 0, 15, 45, 135
D. 15, 45, 135, 405
B. 5, 15, 45, 135
To solve the expression 5 • 3n, we can multiply 5 by each value of n.
Let's substitute different values for n and solve the expression:
For n = 1, 5 • 3(1) = 5 • 3 = 15
For n = 2, 5 • 3(2) = 5 • 6 = 30
For n = 3, 5 • 3(3) = 5 • 9 = 45
For n = 4, 5 • 3(4) = 5 • 12 = 60
So, the correct answer is A. 15, 30, 45, 60.
