Answer these four questions 40 points

1.) Like terms, are similar terms that share a variable, or both don't have a variable.

Example- 4x + 9x =  13x

Since they both have the same variable, you are able to combine them (add them)

2.) Distributive property lets you multiply a sum by multiplying each addend separately and then add the products. Its different from other properties because the commutative property has two elements and one operation, while the associative has three elements and two operations

Example-  4( 5 + 2x). You take the 4 and multiply is to the 5 and 2x, and get 20 + 8x

3.) 3x + 4 = 16. <<<< That's an example of a two - step equation.

    3x = 12

     x = 4

4.) An inequality is a relation that holds between two values when they are different. And no, you would not use them in the real world.

I worked really hard on this. Hope it helps :))

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
