X:{a, b, c}, because the numbers(or letters in this problem) cannot repeat.
4.92.
4 is a whole number, so it goes in the ones place
The ths means it is going to be a decimal, so 92 goes two right of the decimal point. Hope this helped
Answer:
If you are reffering to GCF then the GCF would be explained like this
Find the prime factorization of 18
18 = 2 × 3 × 3
Find the prime factorization of 60
60 = 2 × 2 × 3 × 5
To find the gcf, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3
GCF = 6
The temperature that is 23 degrees above freezing is 55 because the freezing level is 32 and you add 23 to that
