Answer:
Step-by-step explanation:
Least common multiplue is the smallest number that the 2 numbers can multiply into so exg LCM of 3 and 2 is 6,
to find, find the factors
12=2 times 2 times 3
18=2 timeds 3 times 3
so combine all of them
in 12, we have 2 2's and 1 three
in 18, we have 1 2 and 2 3's so
we must have 2 2's and 2 3's so
2 times 2 times 3 times 3=36=lcm\
so find factors and group
lcm=36
25 gallons. you divide 95 liters by 3.8 liters to convert to gallons
The answer is <span>a. T(n+1)=1/2n^2+3/2n+1
</span>
T(n) = 1/2n² + 1/2n = 1/2(n² + n)
T(n + 1) = 1/2((n+1)² + (n+1))
(a + b)² = a² + 2ab + b²
(n + 1)² = n² + 2n + 1
T(n + 1) = 1/2(n² + 2n + 1 + n + 1) =
= 1/2(n² + 3n + 2) =
= 1/2n² + 3/2n + 1
Answer:
The answer is the second one
