The GCF is the smallest shared prime factor for each term.
The LCM is the smallest whole number that both numbers share as multiples.
For example, take #16.
Factors of 25: 1 , 5, 25
Factors of 75: 1 , 3, 5, 15, 25 ,75
The GCF that is shared would then be 25.
The smallest multiple that both share as multiples:
Multiples of 25: 25, 50, 75, etc.
Multiples of 75: 75, etc.
The LCM that is shared would then be 75.
16) 25 and 75
GCF: 25
LCM: 75
17) 35 and 5
GCF: 5
LCM: 35
18) 27 and 36
GCF: 9
LCM: 108
19) 21 and 56
GCF: 7
LCM: 168
20) 54 and 72
GCF: 18
LCM: 216
Factorizing the denominator gives

Then the partial fraction decomposition would take the form

Answer:
C
Step-by-step explanation:
The perimeter of a figure is found by adding the sides of all the figures. The figure has sides 13 and 9. Its height is 4 so each of those sides is about 4 feet. So the perimeter is 13+9+4+4 = 30
C is the best solution.
Answer:
only red = 1/12, only water proof = 1/12 , only cool = nil we assume nil for toys with three collections( cool, red, waterproof) as it was not stated.
11/6 are neither red, water proof and cool.
Step-by-step explanation:
outside the circles contain probability of neither red, cool and water proof. where the circles intersect shows probability of both either red and cool, water proof and cool and water proof and red etc. where all the circles intersect if for the three combinations which is nill. Attached is the diagram
Answer:
Alana is 13 years old.
Step-by-step explanation:
Assuming you meant Mazo = Maisel,
You start from the bottom:
Amelia is 10 years younger than 17-year-old Maisel.
Amelia is 7 years old. (17-10)
Ernie is 2 years older than 7-year-old Amelia.
Ernie is 9. (2+7)
Alana is 4 years older than 9-year-old Ernie.
Alana is 13 years old. (4+9)
Hope this helps!
