Answer:
The least common denominator of the two rational expressions is
.
Step-by-step explanation:
Let be the following rational expressions:

Then, we factor each denominator:

Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:


Hence, we conclude that least common denominator of the two rational expressions is
.
Answer:
A. m =
Step-by-step explanation:
<em><u>The variables "ma" are connected, implying they are together through multiplication. To remove "a" from "m," you must do the opposite, which is division. So, divide both sides by "a," like so:</u></em>
F = ma

= m
Given the amount of water needed to fill the cement dam and the water pump rate, the time needed to fill the dam is 400 minutes or 6hours 40minutes.
Option B)6h 40min is the correct answer.
<h3>How long does it take to fill the dam?</h3>
Given that;
- Amount of water needed to fill the dam A = 30000 litres
- Pump rate r = 75 litres per minute
- Time needed to fill the dam T = ?
To determine how long it take to fill the dam, we say;
Time need = Amount of water needed ÷ Pump rate
T = A ÷ r
T = 30000 litres ÷ 75 litres/minute
T = 400 minutes
Note that; 60min = 1hrs
Hence,
T = 6hours 40minutes
Given the amount of water needed to fill the cement dam and the water pump rate, the time needed to fill the dam is 400 minutes or 6hours 40minutes.
Option B)6h 40min is the correct answer.
