First one, you're trying to solve 2(x + 6) = 22.2

2x + 12 = 22.2

2x = 22.2 - 12

Can you take it from there?

Second one (which you left out half of), the domain is the set of x values, which are the first elements of each ordered pair. So -3 is the first one. Write a set containing all those first elements, and don't repeat anything. If it occurs twice, just list it once.

i will positioned it hassle-free for you: a relation makes an ordered correspondence between 2 units: the area and the co-area. it is represented in ordered pairs that look like this: (element of area , element of co-area) So is you want to locate the area look on the left components of the pairs: -4, -2, 0 and 3 ---> it is your answer. If it could have asked you for the co-area or the photos you could have looked on the best components.
