I have a LCM and GCF homework can someone help i dont understand??
Sindrei [870]
Alright,

So LCM stands for "least common multiple"
While GCF is "greatest common factor"

Let's look at your number 1 (3&6)

3,6,9,12
6,12,18,24

Both times table has 6 in them making 6 the LCM

To find the GCF we need to know what can go into 3 equally. Since 3 is prime the greatest factor for 3 is....3. 6 goes into 3 two times so 3 is the GCF.

LCM:6
GCF:3

Lets do number 10 (40&4)

For LCM you see whats the smallest number that is in both times tables

4,8,12,16,20,24,28.......40
40,80, 160....

40 is the LCM because 40 is what's the smallest number between the two

GCF?

4 times 1 equals 4. Nothing bigger than 4 can make 4 (if your multiplying). That makes 4 automatically the GCF. :)

Which of the following is an example of the associative property?
Mariulka [41]
Hey there!

Let's look at this one answer at a time. 

2(5 - 3) = 10 - 6 would classify as the distributive property because 2 times 5 is 10 and 2 times negative 3 equals negative 6. 

-7 + (19 + 5) = (-7 + 19) + 5 would classify as an example of the associative property of equality because both sides of the equation simplify to equal the same number, 17.

11 + (6 + 8) = 11 + (28 + 6) is not a property of equality because it simplifies out to be 25 = 45 which is not true. 25 can never be equal to 45. It's no solution.

1/3 * 3 = 1 would be a great example of the inverse property of multiplication because one third is the reciprocal of three. In other words the equation could look like this:  1/3 * 3/1 = 3/3 = 1

Hope that helps! Thanks for using Brainly!

Im a little bit confused with square roots and negatives. For example, the square root of 9. Can the square root of 9 be either
stiv31 [10]

Answer:

Yes it can!!

Step-by-step explanation:

Obviously 3^2 is 9 because 3x3 lol

but since -3^2 is multiplying a negative times a negative, that makes a positive (9)
