Andy and Samantha are performing an experiment in a science lab. The number of bacteria cells recorded by Andy in his experiment
is represented by the equation below, where B represents the number of bacteria, x hours after beginning the experiment.
B = 6x + 5
The number of bacteria cells recorded by Samantha in her experiment is represented by the equation below, where B represents the number of bacteria, x hours after beginning the experiment.
B = 2^x + 3

Answer:
Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:
Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":
Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:
Given a quadratic equation 
1. the first thing we do when we want to compete the square, is write the coefficient of x as 2 times a number.
In our case the coefficient of x is 10, so we write 10 as 2*5
2. then we write +
and - to the expression:
