Answer: 36
Step-by-step explanation:
1) Find the prime factorization of 12
12=2*2*3
2) Find the prime factorization of 18
18=2*3*3
3) Multiply each factor the greater number of times it occurs in the first two steps above to find the LCM.
LCM=2*2*3*3
4) LCM=36
Answer:
for 9, the answer is 246.49
Step-by-step explanation:
This is area of a circle correct?
The formula is PI x radius squared.
3.14 x the radius, which is 5, squared
I am re-editing this
so sorry the answer is actually 78.54
The reason why it is 78.54 is that you need to square the radius before multiplying with PI.
Well before the descimal its 5,600 after decimal is 0.56
Completing the square follows the principle of taking
and converting it into
where d is the 'correctional number' as I like to call it - i.e. the number that converts the expanded bracket into the +c, since the expanded bracket will give us
.
In this case, 2/2=1 so we have the first part:
.
Expanding this gives us
. We need c to be 9, so we can just add 8.
Putting this together:
Now we can solve it more easily.
