Henrietta solved a rational equation by multiplying both sides by 
.She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
Henrietta can have got rid of denominator and then use the distributive rule .
So the first option
A:She could use the least common multiple of the denominator is right

The number of bacteria in a colony doubles every 210 minutes.
The population of bacteria = 8000
Determine how many times the population will double.
= 3
Multiply the population by 2 a total of 3 times.
8000 × 2³ = 64,000
Answer:
$20
Step-by-step explanation:
Set up an equation where x is the number of dollars Andrew saved in a month:
50 + x = 60 + 0.5x
Solve for x:
50 + 0.5x = 60
0.5x = 10
x = 20
So, Andrew saved $20
