x+2           (x+2) + 8

-------  =    ---------------

14                14+9

solve by using cross products

(x+2) * (14+9) = 14*(x+2+8)

(x+2)*23 = 14*(x+10)

distribute

23x+46 = 14x+140

subtract 14x from each side

9x+46 = 140

subtract 46 from each side

9x =94

x = 94/4

x = 10 4/9 cm

<h2>Hello!</h2>

The answer is: 50% (0.5)

<h2>Why?</h2>

Exponential growth equations are use to predict the growth (in function of time) using proportional information.

We can calculate the exponential growth using the following formula:

y=S(1+r)^{t}

Where,

S, is the starting value

r, is the growth rate

t, is the time

So, we are given the function:

f(t) = 3(1 + 0.5)^{nt}

Where,

f(t), is the function,

3, is the starting value (lb)

0.5 (50%) is the growth rate

nt, is the time elapsed.

Hence,

From the given function, we know that the growth rate is equal to 0.5, and it's equal to 50%.

We can turn the growth rate given in real numbers to percent value by multiplying by 100

GrowthRate(Percentage)=0.5*100=50(Percent)

So, the growth rate is 50%.

Have a nice day!
