Question:

How can you remember the difference between complementary and supplementary angles?

Inactive
Dani K.

First, we have to remember that one is multiple angles that add to 90 degrees and the other is multiple angles that add to 180 degrees. Since C comes before S in the alphabet, complementary angles add up to equal 90 degrees (the smaller number) and supplementary angles add up to equal 180 degrees (the biggest number).

### Subject:Algebra

Question:

Why can you take a 3 out of 3x-6 but not 3x-5 when simplifying the expression?

Inactive
Dani K.

The first expression has a factor of 3 in both the first and second terms, while the second expression does not. When simplifying the first expression to 3(x-2) you must be able to multiply the 3 on the outside by both x and 2 with the original expression as your answer.
