A good equation would be: f(<em>x</em>)=<em>P</em>(<em>r</em>)^(15). The full equation would be f(<em>x</em>)=<em>P</em>(<em>r</em>/1)^(1(15)), but I just simplified it. <em>P</em> is the initial/principal population of the snails, and <em>r</em> is the yearly rate of growth.
<span> It would depend on the number of rows?
This is an arithmetic sequence and the sum of n terms is -->
n/2(2a+(n-1)d), where a is the first term and d is the common
difference. In this case a = 10, d =6
n/2(20+6(n-1)) = 3n^2 + 7n = ANSWER
n = number of rows

Answer:
.58c
Step-by-step explanation:
Find 42% of c
.42c
Then subtract that from c
c - .42c
.58c
.58c is 42% less than c
-3(x-5)=45
distribute
-3x+15 = 45
subtract 15 from each side
-3x = 30
divide by -3
x = -10
