GCF is greatest common factor, for example the GCF of 4 (1, 2, 4) and 12 (1, 2, 3, 4, 6, 12) is for because that is the biggest factor they have in common.

LCM is lowest common multiple, for example the LCM of 4 (4, 8, 12, 16, 20, 24, etc.) and 12 (12, 24, 36, 48, 60, etc.) is 12 because that is the smallest multiple they have in common.

You really need to know the difference between a factor and a multiple to understand it.

Hope this helps. :)

Convert y + 3 = -3(x + 5) to standard form.
emmasim [6.3K]
Hi there!

y  + 3 =  - 3(x + 5)
First we need to work out the parenthesis, which can for instance be done using rainbow technique.

y + 3 =  - 3x  -  15
Now subtract 3 from both sides.

y =  - 3x  - 18
And finally add 3x to both sides.

3x + y =  - 18
The 4th answer choice is correct.

A certain big company classifies its employees according to gender, age-group (6 categories) and employment type (10 categories)
elena-14-01-66 [18.8K]

We don’t know the number of employees remaining at the company.

We don’t know the total number of employees remaining at the company.

The classification consists of gender, division, and employment type.

It doesn’t matter what order those attributes come in. A person who is male, age group 6, and employment type 10 has the same classification as someone who is of employment type 6, male, and age group10.

Therefore since order does not matter it is a combination question.

Assuming only two genders are allowed (you didn’t say and some people think there are about 10 of them)

It is either 120 (2 times 6 times 10) or "None of the above" if you believe there are more than 2 genders.

2×6×10=120
