1. She made mistake in line c.
2. She added 12 on one side of the equation and subtracted 12 on other side when she was supposed to add 12 on both sides of the equation
Step-by-step explanation:
We will solve the given equation step by step to find her Mistake
a. Distribution property
b. Simplifying
c. Adding 12 on both sides
d. Dividing both sides by 2
By comparing her solution and our solution we can see that she made mistake in line c
So,
1. She made mistake in line c.
2. She added 12 on one side of the equation and subtracted 12 on other side when she was supposed to add 12 on both sides of the equation

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368
mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?
We can figure this out using scientific notation.
Put 3.04e-7 in standard notation.
Put 0.00000304 back into scientific notation, instead with a multiply sign.
Move the dot back, making the number in between 1-10.
In this case, we would move it back 7 times.
