There are several methods for finding the LCM of two numbers, but the easiest for three or more is to use the factor tree method. For example, to find the LCM  9, 6, 21, and 14, use a factor tree for each number as shown.                 ...

Teachers often describe absolute value as the distance a number is from zero on a number line, with distance always being positive. So you could say that the absolute value of -13 and 13 are the same, 13. And 13 minus 13 is equal to 0. However, in this problem, someone left a negative sign next...

It is really important that you remember one rule when factoring: always factor out the greatest common factor first, before factoring with grouping, etc. If you didn't make a typo, yes, add like terms first. If this is the correct problem, I would assume that your teacher is making sure you know...

You can also use the distributive property like this:   2(x + 3) + 4(x + 4) 2x + 6 + 4x + 16 6x + 22   Make sure you multiply every term in the parentheses when using the distributive property. Also, make sure you only add like terms...

Is the triangle isosceles? Do you see tick marks on congruent sides? Then it would make sense.   Ms. B

Since we want the end result to be you and Jay to have an equal amount, you want to set up an equation that way. Each side of an equation is an expression. Equations are like sentences in English, and expressions are like phrases. Many times the variable is what you are looking for; in this case,...
