Solution :

Transforming given equations :

1)\ P = 600( 1 + \dfrac{12}{100})^t\\\\2)\ P = 1000( 1 + \dfrac{3}{100})^t\\\\3)\ P = 200( 1 + \dfrac{8}{100})^t\\\\4)\ P = 900( 1 - \dfrac{10}{100})^t

From above equations we can see that equation 1) has largest percentage growth rate and the percent growth rate is 12% .

Hence, this is the required solution.

Answer: (i), 12%

Step-by-step explanation:

Given

The Population of four towns is given

(i) P=600(1.12)^t i.e.

\Rightarrow P=600(1+0.12)^t\\\Rightarrow P=600(1+12\%)^t

rate=12%

(ii) P=1000(1.03)^t

\Rightarrow P=1000(1+0.03)^t\\\Rightarrow P=1000(1+3\%)^t

rate=3%

(iii) P=200(1.08)^t

\Rightarrow P=300(1+0.08)^t\\\Rightarrow P=300(1+8\%)^t

rate=8%

(iv) P=900(0.90)^t

\Rightarrow P=900(1-0.10)^t\\\Rightarrow P=900(1-10\%)^t

rate=10% fall

So, the largest growth rate is for town (i)  i.e. 12%

The dimensions of the prism can be 2x, 2x+3 and x+6.

We first factor out the GCF of the trinomial.  The GCF of the coefficients is 2.  Each term has an x in common as well, so the GCF is 2x.

Factoring out the 2x, we have
2x(2x²+15x+18).

To factor the remaining trinomial, we find factors of 2*18=36 that sum to 15.  12*3 = 36 and 12+3 = 15.  We split up 15x into 12x and 3x:

2x(2x²+12x+3x+18)

Now we group together the first two terms in parentheses and the last two:
2x((2x²+12x)+(3x+18))

Factor out the GCF of the first group:
2x(2x(x+6)+(3x+18))

Factor out the GCF of the second group:
2x(2x(x+6)+3(x+6))

Factoring out what these have in common,
2x(x+6)(2x+3)
