(2m)/(2m+3)-(2m)/(2m-3)=1
Simplifying the left hand first
(2m)/(2m+3)-(2m)/(2m-3) = {2m(2m-3) - 2m(2m+3)}/(4m²-9)
(4m²-6m-4m²-6m)/(4m²-9)
= (-12m) / (4m²-9)
Now this equet to 1
(-12m) / (4m²-9) = 1
-12m = 4m²-9
4m²+ 12m -9 =0 ⇒⇒⇒ This is a quadratic equation that has 2 real solutions.
4m²+ 12m -9 =0
m² + 3m + (3/2)²= 9/4 + 9/4
(m + 3/2)² = 18/4
m = √18/2 - 3/2 or m = -√18/2 - 3/2
= 0.621 = -3.621
So we can say that the equation has NO extraneous solutions.
Answer = 0
Answer:
the correct answer is 34267.6
Step-by-step explanation:
10^4 power is 10000 and then times 3.426760 = that
Circumference = 2 x radius x Pi
Circumference = 2 x 15 x 3.14
Circumference = 30 x 3.14
Circumference = 94.2 feet
Answer:
<em>4 pounds of ingredients are used in each batch.</em>
Step-by-step explanation:
Amount of flour = 
Amount of butter = 8 pounds
Amount of sugar = 
So, the <u>total amount of all ingredients</u> will be: 
Given that, she makes 12 batches of cookies using all the ingredients.
Thus, the amount of ingredients used in each batch
