5/6 I think tahts the answer hope this helps
Since the variable x has an invisible one next to it, which is 1x, it is 6x.
Answer: 45
Step-by-step explanation:
The sides are 2x,3x,4x
Add them up and you have 9x=45
Using an exponential function, it is found that the colony will have 1344 bacteria after 8 days.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
Considering the initial amount of 150, and the growth rate of 73% each 2 days, the equation is given by:

Hence, after 8 days, the amount of bacteria is given by:

3 (4x + 6) = 21
4x + 6 = 21/3
4x + 6 = 7
4x = 7 - 6
4x = 1
x = 1/4
