Prime numbers have?
-less than two factors
-more than two factors
-exactly two factors
-less than or equal to two factors

exactly 2 factors

Step-by-step explanation:

they are 1 and itself

for example 3 is a prime number and its factors are 3 and 1.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
