Answer:
17.5
Step-by-step explanation:
You have to find n right?
9+4n-79 = 0
-> 4n = 70
-> n = 17.5
Answer:
60
Step-by-step explanation:
Just use similar triangles.
12/10 = 72/x
Now solve for x.
x = 72 * 10 / 12 = 60
Answer:
486, 486r,486r^2,486r^3,486r^4,2
------------------------------------
2 = 486r^5
-----
r^5= 1/243
----
r = 1/3

Step-by-step explanation:
Answer:
1, 3, 9, 27
Step-by-step explanation:
You need the first 4 terms, so let n = 1, and evaluate the expression. Then do the same for n = 2, n = 3, and finally n = 4.
n = 1
n = 2
n = 3
n = 4
