You take out the biggest factor of 9 and 36 which is 9c^2. The factors both have the c variable in common so you take the least exponent and put it with the gcf.

9c^2(c^2+4)

You would do
(3c^2+6c)(3c^2-6c)
since 3c^2 squared becomes 9c^4
and 6c times negative 6c becomes -36c^2

I just checked over and it would become
3c^2+6c[3c(c-2)]

An exponential model shows the growth of a towns population in years. Identify the parts:

Semmy [17]

9514 1404 393

Answer:

2% growth per year
25,000 to start
12 years
31,706 currently

Step-by-step explanation:

The base of the exponent is (1 +0.02). The value 0.02 = 2% is the growth rate. It is positive, signifying a 2% rate of growth per year. (Negative values would mean decay.)

The number 25000 that multiplies the exponential term is the value of the expression when the exponent is zero. It represents the starting population.

The exponent is said to be in years, so the time is 12 years.

The current population is the value of the expression:

25,000(1.02^12) ≈ 31,706 . . . . current population
