To Find the least common denominator you have to find the multiples of each number
multiple means the product of each factor
so the multiples of 4 would be 4 8 12 16 20
you want to name at least five multiples but if there are not the same multiples you might have to list more
the multiples of 5 would be 5 10 15 20
then I can stop there because I have found two of the same multiples
so now we have our least common denominator which is 20
HOPE THIS HELPS!!!
Answer:
0.5
Step-by-step explanation:
Ok, so it's asking for what (1/(x-1) - 2/(x^2-1)) approaches as x approaches 1. Before we deal with the limit, let's simplify the inside.
We want to combine the two fractions into one fraction. Therefore, we need a common denominator.
1/(x-1) is equal to (x+1)/((x+1)(x-1) is equal to (x+1)/(x^2-1).
the inside expression is therefore (x+1)/(x^2-1) - 2/(x^2-1)
which simplifies to (x-1)/(x^2-1).
and that simplifies further to 1/(x+1).
Now this is a continuous function when x = 1, so to find the limit as x approaches 1 of this function, we can by definition just plug 1 in.
limx->1 (1/(x+1)) = 1/2.
The reason why we didn't just plug 1 in at the beginning is because the function wasn't continuous when x was 1.
Add the three strips of cut wood together:
John will need to cut a total of 50.05cm of wood.
Subtract this total from the strip John has:
The leftover piece will be 21.95cm long.
Answer:
$100
Step-by-step explanation:
He gets paid a commission of $400 for a $100,000 insurance policy. We need to find out how much he's gonna get paid for a $25,000 insurance policy.
Break down the $100,000 into four equal amounts if possible, which it is:
$25,000
$25,000
$25,000
$25,000
Now break down his commission of $400 for the $100,000 insurance policy into four equal amounts if possible, which it is:
$100
$100
$100
$100
Now since we split them up into four equal parts you can tell how much he would get paid for a $25,000 insurance policy.
He would get paid $100 for the $25,000
Answer:
The correct answer is 3. -88
Step-by-step explanation:
24 / 3 + 24 x -4
24 x -4 = -96
24 / 3 = 8
8 + -96 = -88
