NEED HELP ASAP WILL GIVE BRAINLIEST REAL ANSWERS ONLY PLZ WILL REPORT FAKE ANSWERS

D

Step-by-step explanation:

Well, f(1) is when n = 1, so if you check the graph, it shows that when n = 1, f(n) = 4. Therefore, f(1) = 4

Next, we find the pattern between each f(n) when we increase n by 1

When n = 1, f(n) = 4

When n = 2, f(n) = 20

When n = 3, f(n) = 100

Notice that when we increase n by 1, f(n) multiplies by 5

4 x 5 = 20

20 x 5 = 100

Thus, we know that the common multiple of 5, for choice D.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
