This will only have one solution because it does not deal with a quadratic. Then to isolate x you need to get the similar terms on different sides by subtracting or adding, Then divide both sides by the number next to x (coefficient).
4.24 is the answer I believe,
You would have to plot the vertices and play a sort of game of connect the plots ( *Or connect the dots but more literally, the plots*) Then decide whether or not your final illustrations have the potential to be similar. If so, why?
EXAMPLE ANSWER: DO NOT USE ANY IF THEM BELOW FOR I DO NOT KNOW THE UNIT LENGTH OR SHAPE THE CONNECTED DOTS WOULD CREATE!!!
The two triangles could be similar due to the identical amount of units between each vertice. Furthermore, you could connect the units in a certain orientation, keeping the units in mind, and produce two identical triangles.
Or...
The two triangles could be similar due to the type of triangle. Each triangle has the potential to be a (right/scalene/isosceles/obtuse/acute, etc).
1 + 1 + 20 cents + 3 cents = $2.23
Its right and isosceles because the little squares means that's it's a right triangle. And the lines means it's identical which an isosceles has two identical lines
