The answer is ( x - 3 ) ( x - 5)
1/4(8m - 4n) + 1/3(6m + 3n)=
Distribute the fractions through the parentheses
2m - n + 2m + n =
Combine like terms
2m + 2m - n + n = 4m
The answer is 4m
I'm assuming that subtraction sign is mean to be an equals sign. If that is true than the answer is 403.75.
I can help you with #20. For example, lets say 3/5, this fraction would be made up of 5 parts and 3 are covered, which doesn't make it full, if it was 5/5 it would be full. When you do something with a reciprocal you turn it over, so 3/5 would be turned over to 5/3, thus making it a whole number
Answer:
The correct answer to the following question will be "384".
Step-by-step explanation:
We are having,

On solving, we get
⇒
