Prime numbers are those that cannot be divided by another number (other than themselves and 1). In other words, prime numbers have factors of themselves and 1.
For example, 3 is a prime number because its only factors are 3 and 1.
6 is not a prime number because it can be factored to 3*2.
Therefore, the correct answer is c. 3,11,23,31
The Olmecs (/ˈɒlmɛks, ˈoʊl-/) were the earliest known major civilization in Mesoamerica following a progressive development in Soconusco. They lived in the tropical lowlands of south-central Mexico, in the present-day states of Veracruz and Tabasco. It has been speculated that the Olmecs derive in part from neighboring Mokaya or Mixe–Zoque.
Answer:
56-7m
Step-by-step explanation:
l7m–56l m<8
so lets replace m with something smalller then 8, how about 7
so then it would be...
l 7 * 7 - 56 l=
l 49-56 l = l -7 l
but the absulute value of -7 is 7, so how does this help us? well lets see
56-49= 7 this proves that all we have to do is switch the order giving us the solution 56-7m
hope this helped :)
