Hey there! I'm happy to help!
A prime number is a number whose only factors are one and itself. 5 is a prime number because the only whole numbers you can multiply to get 5 are 1 and 5.
Prime factorization is finding the prime numbers that multiply to make that number.
To do this, you see what numbers it divides by. 15 is divisible by 1, giving us 15. It is not divisible by 2, but it is divisible by 3, which gives us 5.
Now, we see if 3 and 5 can be factorized even more, but they cannot as they are both prime numbers. Therefore, the prime factorization of 15 is 3,5.
Have a wonderful day! :D
Answer:
b<11
graph it on a number line by putting an open circle on 11 and go over the line darker on the rest of the line ONLY TO THE LEFT OF THE CIRCLE ON 11 ALL THE WAY TO THE END OF THE LINE !!!TO THE LEFT!!!!
Step-by-step explanation:
Answer:
-6(3a + 5)
Step-by-step explanation:
Factoring -6 from 18a, you will be left with 3a because -6× 3a will give you 18a
Also factoring -6 from 30, you will be left with 5 because -6 ×5 = -30.
so -18a -30
-6( 3a + 5)
Correct answer is (median is 21)
