Answer:
Hey there!
15 is composite. A composite number has factors other than one and itself. 15 has factors 3 and 5.
Thus, 15 is composite.
Let me know if this helps :)
The ratio is common, so you could write:
a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)
Plug in the values:
3 * r^4 = 48
Divide by 3:
r^4 = 16
Take the fourth root of both sides:
r = 2
The common ratio is 2.

Answer:
62
Step-by-step explanation:
The total of a triangle is 180
so 78+48 is 118
180-118=62
7a^2b + 10a^2b^2 + 14a^2b^3 =
a^2b (7 + 10b + 14b^2) <==
