Answer 2

=3^-2=1/9

Answer 3

1/9

Answer 7

ok, my bad raheen is right then

Answer 8

its alright

Answer 9

PLEASE HELP ME!

Answer 10

in need help with gcf and LCM

Answer 11

Ok, what is confusing you about it?

Answer 12

every thing im a student and i guess i learned it wrong:(

Answer 13

im so confused

Answer 14

haha ok i will try to explain it the best I can. So GCF is where you have a polynomial and you need to simplify by finding a common factor. 64x^3+32xy^2+16x^2y for example the GCF of this would be 16x because 16 is the most I can take out of this and is the highest power I can take out. As for LCF i am confident enough to explain that one. I this kinda hleps

Answer 15

the problem im working on is what is the common factor for 16 and 48

Answer 16

I think that is 16 because you can divide 16 from 48 and get 3

Answer 17

i have alot of homework

Answer 18

What does the back of the book say?

Answer 19

6 isnt in the answer choices

Answer 20

Could you tell me what the choices are?

Answer 21

16 i mean

Answer 22

768,24,12,8

Answer 23

If it is just one answer then it would be 8. I believe this to be true because 8 is the biggest number you can take out of both without getting rid of either one. That is what I took from it.

Answer 24

ok thank you

Answer 25

i guess that kind of makes sence

Answer 26

Try that on the next problem, look for the highest number you can divide out of both without losing either number. I hope this helps some

Answer 27

ok well the next problem says what is the gcf of 28 and 42

Answer 28

Ok, based on previous problems what do you think it might be?

Answer 29

maybe 7

Answer 30

That is what I got. Check your answer and see

Answer 31

im trying to c if 14 will work

Answer 32

Haha my bad that one works as well

Answer 33

14 works!!

Answer 34

yay!!! so 14 is the answer

Answer 35

It seems like you have the hang of it. It only gets harder because the numbers usually get bigger or they word it weird

Answer 36

awwwwwwwwwwwwwwwwwwwww man........ the next promblem is a word problem

Answer 37

Hahah those are never too fun. All you really need to worry about is the numbers in problem just write out what you read in an algebraic form or something similar or easy for you to understand

Answer 38

neli has 25 candies 18 peppermint and 12 chocolate candies he wants to divide the into groups so that each group has the same numbers of each candy. whats the largest group neli can make?

Answer 39

So we know that each group together has to equal 25 so we need to find a common factor in each that equal 25.

Answer 40

NOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! im stuck:(

Answer 41

ohh sorry instead of 25 its 24 candies

Answer 42

i have a test tomarrow im scared

Answer 43

ahh dont be scared you will do fine. I am trying to think of how to make this make sense

Answer 44

umm i know 2 goes into all of them

Answer 45

12 goes in to 24 and 12 but not 18

Answer 46

umm i think the answer is 12

Answer 47

I KNOW THE ANSWER IS !@ BECAUSE THATS THE HIGHEST NUMBER THAT CAN GO INTO ALL OF THEM!!

Answer 48

One thing wrong with that though 12 is not a factor of 18. Ok so what did you come up with?

Answer 49

:( i forgot about the 18

Answer 50

okkkk.... so then the answer is 6

Answer 51

I believe 6 is the answer

Answer 52

But I am a little sketch about it because it feels like there is something missing, can you see the answer in the back of the book

Answer 53

okkkk what is the least common multiple of 4 and 12??? b:12

Answer 54

for least I would think 1 maybe, but that seems to easy so my next guess is 2

Answer 55

what is the least common multiple of 20 and 30?

Answer 56

1 and 2 are not on the answer choices

Answer 57

60

Answer 84

hello?

Answer 85

Ok so here you figure out each multiple of both numbers until you find one that is common
10=10,20,30,40,50,60,70,80...
12,24,36,48,60
so he will need to buy five of each
