C
Step-by-step explanation:
You do 5 - 2 = 3 and -y = -x so the answer would be C.
V = s³
v = (1.2s)³
v = 1.728s³
1.728 * 100% = 172.8% increase
The answer is 5x^2y. The lowest exponent would be the GCF for each term if it has one
This is a geometric progression problem. We can the general formula that can tell us how many flowers would be planted each month.
Let's write the terms that we know and see if we can find the pattern:

The patern here is obvious. Let's write it down:

This formula gives us a number of flowers planted in the n-th month.
12^2+x^2=15^2
144+x^2=225
- 144 -144
=81= 9
X=9
