141

Answer 19

\[-8\times 5=-40\neq 40\]

Answer 20

oh another question

Answer 21

im not done

Answer 22

111 is divisible by 3 since \(1+1+1=3\)

Answer 23

\[121=11^2\] not prime

Answer 24

but it asks which is prime

Answer 25

141 is also divisible by 3 since \(1+4+1=6\)

Answer 26

as usual, it is C 131

Answer 27

you now how to tell if a number is divisible by 3?

Answer 28

Determine the prime factorization of 99.



34


34• 2 • 5


34• 11


32• 11

Answer 29

??

Answer 30

HOW

Answer 31

\[99=9\times 11\] right ?

Answer 32

ye

Answer 33

and since \(9=3\times 3\) that means \[99=3\times 3\times 11=3^2\times 11\] which does not see bot be one of your choices

Answer 34

mhm

Answer 35

unless your last choice is \(3^2\times 11\) and not \(32\times 11\) which is what you wrote

Answer 36

mhmm

Answer 37

so d

Answer 38

yeah D

Answer 39

alright

Answer 40

Determine the prime factorization of 476.



22 • 32 • 13


22 • 7 • 19


22• 7 • 17


2 • 35

Answer 41

donkey work

Answer 42

hay im tryin

Answer 43

want to do it the long boring way ?

Answer 44

no

Answer 45

wanna do the ' i learn ' it way

Answer 46

>:)

Answer 47

ok then it is clear that \(476\) is divisble by 2 right, because it is even

Answer 48

yass

Answer 49

ok so step one is find half of \(476\) i.e. divide it by 2
what do you get?

Answer 50

238

Answer 51

ok so step one \[476=2\times 238\] but \(238\) is also even, what is half of 238?

Answer 52

119

Answer 53

ok so we are at \[476=2^2\times 119\]
119 is not even, s it is not divisible by 2

Answer 54

\[1+1+9=11\] so it is not divisible by 3

Answer 55

it is obviously not divisible by 5

Answer 56

try 7

Answer 57

k

Answer 58

17!

Answer 59

took me awhile to process that

Answer 60

ok so \[476=2^2\times 7\times 17\]

Answer 61
